Introducing Hybrid Cloud Manager™
vCloud® Air Hybrid Cloud Manager™ enables bidirectional VM mobility and migration to the cloud and back, and hybrid
networking to extend on-premises vSphere vCenter networks into vCloud Air.
Data transport features: network extension, WAN optimization, Multi-tenant WAN with Intelligent Routing, and path
fail-over.
Security features: Suite B-compliant AES-GCM with IKEv2, data deduplication and compression, AES-NI Offload, Flowbased Admission Control. Hybrid Cloud Manager owns the source and destination encryption and decryption, ensuring a
consistent security policy and providing admission for hybrid workflows like virtual machine migration and network
extension.
Hybrid Cloud Manager features can be deployed in several ways:
• Hybrid Networking (Layer 2 Extension). Securely extend your vSphere vCenter to integrate with a vCloud Air Virtual
Data Center (vDC). Configure networking connections to support high-speed connections.
• Can stretch multiple L2 segments
• Can route stretched networks via Cloud Gateway for encryption and through the WAN optimization appliance to
provide a secure and optimized path through the Internet to vCloud Air
vCloud Air® Hybrid Cloud Manager™ Installation and Administration Guide
Page 5
• Dedicated scale out L2 Concentrators can be deployed and used in conjunction with Direct Connect to increase
throughput
• Multiple Direct Connects and fail-back to Internet are supported
• Extended Networks are linked to vCloud Air Advanced Network Services Edge appliances in Org Gateway
position and can be announced back to the Enterprise once all virtual machines are migrated and the network is
unstretched
• Egress path optimization (optional) to allow shortcut routing between virtual machines on different stretched
networks in the Cloud
• Low-downtime Migration. The Hybrid Cloud Manager migration process creates a replica of a live VM, which is then
moved to the target vDC, then performs a switchover to power off the source VM and power on the replica. You can
migrate over the public internet, a dedicated line (such as Direct Connect connection), or a stretched network
created with Hybrid Cloud Manager.
• Migration uses vSphere Replication, which is a distributed technology implemented in the ESX hypervisor.
• A virtual machine can be migrated multiple times in either direction.
• Migration can be set to occur at a specified time.
• A migrated VM can keep its host name and/or VM name.
• Speed up migration or stretched network performance with optional software-defined WAN optimization.
• Migration over Stretched Layer 2:
• VMs migrated over stretched L2 can retain their IP and MAC. With consistent IP and MAC addresses,
applications can continue to work after migration.
• Can separate the data path from the migration path and still take advantage of dynamic routing.
Understanding the Hybrid Cloud Manager Installation Process
Hybrid Cloud Manager supports a many to many relationship between on-premises vCenter(s) and vCloud Air virtual
datacenters (vDCs). The vCenters in Linked Mode are also supported. Please reference recommended vCenter Linked
Mode topologies for the version of vSphere in use.
During the installation, the Hybrid Cloud Manager virtual appliance is imported and configured as an extension in the
on-premises vCenter. Then you can install and configure the Software-Defined WAN virtual appliances. During the
configuration phase, the automated installation workflow provisions each virtual appliance in your on-premises vCenter,
and creates a corresponding, symmetrically-deployed virtual appliance in your vCloud Air vDC.
After the installation, Hybrid Cloud Manager controls both local and remote installation components. In your vCloud Air
vDC the provisioned Software-Defined WAN components are managed as a service, and as such they are not editable, or
even visible, in your vCloud Air vDC.

Installation Overview
This is a brief summary of the Hybrid Cloud Manager installation tasks.
1. Identify the architecture you want to use (see “Use Cases”).
2. Log into My VMware and download
https://my.vmware.com/en/group/vmware/details?downloadGroup=HCM100&productId=343
3. From vSphere, install the Hybrid Cloud Manager virtual appliance in the on-premises vCenter that will connect to
vCloud Air.
The management interface and the virtual appliances must be in the same vCenter. If you plan to use L2 network
extension, a VMware virtual distributed switch (vDS) must also be available in the same vCenter. See “Preparing
Your Installation Environment” for more configuration details.
4. Register a vCloud Air Endpoint with the vSphere web client.
This step establishes the one-to-one relationship between the on-premises vSphere vCenter and a vCloud Air cloud
instance.
5. Install and configure the hybrid service appliances. For each appliance installed on premises, the installer provisions
a VM in the target vCloud Air vDC. The service appliance configuration determines the feature deployment
architecture (see “Installing and Configuring Hybrid Services”).
the Hybrid Cloud Manager OVA file from the product download page:
Hybrid Cloud Manager Virtual Appliances
The installation package includes the Hybrid Cloud Manager and three hybrid service appliances, each of which is
deployed as a VM. The VMs are automatically provisioned and sized, as shown in Table 1.
vCloud Air® Hybrid Cloud Manager™ Installation and Administration Guide
Page 7
Table 1: Virtual Machine Installation Resource Requirements
VM vCPUs RAM Installation
Hybrid Cloud Manager 4 12 GB Required.
Hybrid Cloud Gateway 2 2 GB Required.
Layer 2 Concentrator (L2C) 6 8GB Optional for migration, required for stretched Layer 2, or migration over stretched Layer 2.
WAN Optimizer 8 14 GB Optional.
During the installation process you can choose the Cluster/Host that will host the VMs for the Hybrid Cloud Manager,
the Hybrid Cloud Gateway, and the Layer 2 Concentrator (L2C). The WAN Optimizer is automatically deployed to a host
that best meets its requirements (as determined by vSphere at the time of the installation).
Hybrid Cloud Manager
The Hybrid Cloud Manager virtual appliance is Installed on-premises only and contains all other virtual appliance onboard, simplifying the download and the installation process.
Hybrid Cloud Gateway
The Cloud Gateway maintains a secure channel between vSphere and a vCloud Air. The channel secures access for
vSphere protocols that are not tenant-aware, and provides intelligent routing capabilities to avoid networking "middle
mile" security problems. Since the Cloud Gateway uses strong encryption, no corporate VPN changes are required for
Hybrid Cloud Manager functionality.
The Cloud Gateway also incorporates vSphere replication technology to perform bidirectional migration. For more about
vSphere Replication usage and virtual machine migration, please see “Understanding Replication-Based Migration,” on
page 30.
Layer 2 Concentrator
The Network Extension Service extends a network from a vSphere Distributed Switch (vDS) to a vCloud Air.
The Layer 2 Concentrator (L2C) service appliance functions as a translation bridge to extend VLANs to VXLAN in vCloud
Air or as a transparent bridge when VXLAN and NSX-vSphere Edition is used on-premises. It has two interfaces:
• Internal Trunk interface: handles virtual machine traffic on-premises for the extended networks.
• Uplink interface: encapsulated overlay traffic is sent via this interface to and from vCloud Air.
When the virtual appliance is configured, you can masquerade the L2C behind the Cloud Gateway and share its IP
address. This allows ease of install in that the Cloud Gateway, L2C, and WAN Optimization appliance only require one IP
address. This is possible when selecting the deployment option where Extended Network traffic is routed via Hybrid
Transport (via Cloud Gateway). It is also possible to use a unique IP address for the L2C, thereby separating the
migration path and the stretched network data path. The latter approach is used in conjunction with scale out
deployment for multiple L2Cs and when using Direct Connect private lines where strong encryption may not be required
for extended networks.
WAN Optimization
The WAN Optimization appliance is an optional, yet highly recommended, component that performs WAN conditioning
to reduce effects of latency, Forward Error Correction to negate packet loss scenarios, deduplication of redundant traffic
vCloud Air® Hybrid Cloud Manager™ Installation and Administration Guide
Page 8
patterns to reduce bandwidth usage and insures best usage of available network capacity to expedite data transfer to
and from vCloud Air.
• Virtual machine migration relies on the combination of Cloud Gateway and WAN Optimization appliance to achieve
unparalleled mobility between vSphere on-premises and vCloud Air
• L2 extension benefits from WAN optimization when the data path is routed through the Cloud Gateway (Hybrid
Transport option in the workflow)
Choosing a Deployment Architecture
The most common use case is to install the Hybrid Cloud Manager and all three types of Software-Defined WAN
appliances, as shown in Figure 1 on page 7. Table 2 summarizes the possible use cases, and what the minimal installation
entails.
A single path architecture uses the Cloud Gateway for all communication.

Migration Only
In Table 2, cases ❶ and ❷ are for migrating without an L2 extension. Other than the Hybrid Cloud Manager, only the
Hybrid Cloud Gateway appliance is required. The basic difference between cases
possible with the Hybrid Networking Premium option.
WAN optimization, if installed, can improve security and speed in the situations described in “WAN Optimizer” on page
8. If you have a secure high-speed line (for example, Direct Connect), configuring the Hybrid Cloud Gateway to use that
line is another way to improve speed.
One advantage of migrating virtual machines on extended networks into vCloud Air is that the downtime is reduced to a
few minutes and no configuration changes happen on the virtual machine. The virtual machine can retain the MAC
addresses, computer names and VM names – greatly simplifying the migration to vCloud Air and enabling easy round
trips back on-premise, when needed. The Network Extension feature requires a vSphere Distributed Switch, which
requires vSphere Enterprise Plus Edition.
It is possible to migrate virtual machines without network extension. In this case the virtual machine obtains a new IP
address via the Guest Customization service once it is migrated.
IP Addresses for Installation: 2 on-premises, 1 for vCloud Air vDC
❶ and ❷ is that higher speed is
Layer 2 Extension
Before you configure L2 network extension, you must be certain that you have the prerequisites, as explained in, “Verify
Layer 2 Installation Requirements.”
Use cases 3-7 rely upon Layer 2 Extension. You can view Layer 2 Extensions as a way to extend or stretch your onpremises network to vCloud Air, enabling seamless VM migration between the data center and the cloud. For example,
suppose you have an application and a database on separate hosts in your vCenter, and you migrate the application into
the Cloud.
• If you are using Hybrid Transport in the deployment wizard (single path approach), the migration and extended
network traffic is routed through the Cloud Gateway. WAN optimization (if installed) and intelligent routing will be
applied to migration workloads and the extended network data path.
• If the migration path and the data path are separate (cases 5, 6, and 7), the Cloud Gateway still maintains the secure
channel and handles migration workloads, which get the benefits of WAN optimization (if installed). The extended
network data traffic between virtual machines travels on the routes configured for the Layer 2 Concentrator(s).
The remainder of this section summarizes how L2C configuration affects the Layer 2 Extension use cases.
Single Path
This is the default service appliance deployment, where the L2C and WAN optimization appliances use the same IP
address as the Cloud Gateway.
IP Addresses for Installation: 2 on-premises (HCM, Hybrid Cloud Gateway), 1 for vCloud Air vDC
vCloud Air® Hybrid Cloud Manager™ Installation and Administration Guide
Page 10
Separate Migration and Data Paths
The Cloud Gateway and the L2C service appliances use different outbound IP addresses. In this configuration, the L2C
appliance data path does not benefit from WAN Optimization or intelligent routing, but workloads travelling through the
Cloud Gateway do. This might not be an issue if the host-to-host traffic on the data path is already encrypted or
compressed.
IP Addresses for Installation: 3 on-premises (HCM, Hybrid Cloud Gateway, L2C), 2 for vCloud Air vDC
Scale Out: Multiple Layer 2 Concentrators for the Data Path
Using multiple L2C appliances is most beneficial if you have secure, high-speed lines, such as a Direct Connect lines, and
you want your architecture to support application performance scale out.
For example, if you have multiple vLANs you might choose to configure an L2C for each vLAN. In this architecture the
L2Cs maintain the data path(s) for host-to-host communication but continues use the Hybrid Cloud Gateway for internal
communication, management tasks, and migration workloads.
IP Addresses for Installation: On premises, 1 each for HCM and HYBRID CLOUD GATEWAY, and 1 for each L2C. In vCloud Air, 1 for the Hybrid Cloud
Gateway, and 1 for each L2C.
Other Architecture Considerations
Egress Path Optimization
Egress Optimization is a feature that applies only to the remote vCloud Air vDC network.
You enable this feature when you configure the Hybrid Cloud Gateway, as shown in Step 5 on page 28.
Intelligent Routing.
This feature applies to any traffic routed over the public internet.
Preparing Your Installation Environment
Before installing Hybrid Cloud Manager, verify that your environment can support the tasks you want to accomplish.
Configure Network Connectivity
The Hybrid Cloud Manager, when installed, must be able to reach the public internet and/or your private line(s), and any
necessary data center elements such as networks, switches, port groups, and VMs you might migrate.
Table 3 lists ports that must be opened so that Hybrid Cloud Manager virtual appliances can install successfully.
Also, both your vSphere environment and your vCloud Air environment must allow for Network Time Protocol (NTP)
clock synchronization among vSphere on-premises devices and the vCloud Air Dedicated Cloud devices. UDP port 123
must be accessible to Hybrid Cloud Manager virtual appliances and networks. If you have installed NTP Servers you can
specify them when you install the Hybrid Cloud Manager appliance (step 11.f on page 15).

Verify the Minimum Installation Environment
Before the installation, ensure that you have the following resources in your on-premises vCenter and your vCloud Air
vDC.
On Premises
• An on-premises Virtual Center created with vSphere 5.5 Update 1 or above.
• Administrator access to the source Virtual Center and any resources you want to connect to the cloud.
• In the vCenter, enough disk space for Hybrid Cloud Manager and the appliances you install, as stated in Table 1, and
any replicas remaining from migration. See “Understanding Replication-Based Migration.”
• Sufficient IP addresses for the on-premises VMs provisioned during the installation. The minimum requirements for
each configuration are specified in “Use Cases.”
• Ports and firewalls opened as required.
In vCloud Air
• A vCloud Air Dedicated Cloud subscription account.
• Hybrid Networking Standard or Premium add-on service. See
cloud-manager. You can purchase the add-on with a purchase order, or you can use the VMware Subscription
Purchasing Program.
Purchasing the Hybrid Networking add-on service automatically opens a vCloud Air operations ticket that upgrades
your vCloud Air Edge Gateway to a version with Advanced Network Services feature-set (ANS). Hybrid Cloud
Manager cannot successfully install until the vCloud Air Edge Gateway within the VDC is upgraded to Advanced
Network Services edition and your My VMware account reports the Hybrid Networking add-on service status is
available.
• A virtual datacenter (vDC) with sufficient resources for the appliances you want to install and any virtual machines
you will migrate. You must know the vDC’s username and password, and its IP address, gateway, and DNS
information.
• The target vDC must have at least one available IP address for the Hybrid Cloud Gateway. The “Use Cases” section
estimates the number of IP addresses required for each use case.
Note: If your Dedicated Cloud does not have an available IP address, you can purchase one. Log
into vCloud Air, and from the Dashboard tab click on the target vDC. On the lower right, under
Related Links, click Purchase More Resources. When My VMware opens, click Purchase Addons and add more IP addresses to your service ID. For more about IP addresses in vCloud Air,
see “Allocation of Public IP Addresses
.”
http://vcloud.vmware.com/service-offering/hybrid-
Verify Layer 2 Installation Requirements
To support Layer 2 extension, your vSphere vCenter must meet these requirements:
• Must have a vSphere Distributed Switch
Edition.
vCloud Air® Hybrid Cloud Manager™ Installation and Administration Guide
(vDS). The distributed switch is available with vSphere Enterprise Plus
Page 13
• When installed, the on-premises L2 Concentrator service appliance must have access to a vNIC port and any vLANs
you want to stretch.
• If you choose to stretch a network over the public internet or your own VPN (on an alternate path, not the Hybrid
Cloud Gateway) then the L2C VM in your vCloud Air vDC also requires an IP address. If your architecture specifies
multiple L2Cs, each must have an IP address. You must know the remote IP address before you configure the L2C.
Verify the vCloud Air Edge Gateway Upgrade
To ensure support for Hybrid Cloud Manager you must log into your vCloud Air account and upgrade the target vCloud
Air gateway to support Advanced Networking Services. This assumes you have already purchased the Hybrid Networking
add-on service, and its status is “available,” as described in “Verify the Minimum Installation Environment” for vCloud
Air.
Note: Hybrid Cloud Manager only requires the upgraded Edge Gateway. Your Edge Gateway must be
upgraded to Advanced Networking before you install Hybrid Cloud Manager.
Follow the steps in Upgrade an Edge Gateway to Advanced Networking Services
Service license prerequisite).
(ignore the Advanced Networking
Install the vSphere Web Client Integration Plug-in
You must install the vSphere Web Client Integration Plug-in. With the vSphere Web Client you can use a browser to
connect to a vCenter Server system and manage an ESXi host.
The Hybrid Cloud Manager is delivered as an open virtualization archive (OVA) file. To install an OVA file, the vSphere
Web Client must have the client integration plug-in installed. See the documentation or the video for this task:

Installing and Configuring Hybrid Services
Now that the Hybrid Cloud Manager has been installed and connected to your Dedicated Cloud, you can install and
configure the hybrid service virtual appliances.
During the configuration, most of the information you provide refers to the on-premises (local) VMs. The installer uses
your inputs to provision each appliance both on premises and in vCloud Air.
Configuration Overview
The following procedure assumes that you are configuring all three virtual service appliances, however, they are not all
required.
• The Hybrid Cloud Gateway (configured in Step 1 on page 23) is required.
• To install WAN optimization, just choose the option in Step 4 on page 23 (no further configuration required).
• The Network Extension service is configured in Step 6 on page 24.
If you choose to defer installing an optional appliance, you can always return to the Hybrid Services Configuration wizard
and install the appliance later on. However, removing an appliance requires application downtime (see “Removing
Hybrid Service Appliances”).
Start Appliance Installation and Configuration
1. Log in to the vSphere Web Client. On the Home tab, click the Hybrid Cloud Manager icon.
The Hybrid Cloud Manager pane opens.
2. Click the Hybrid Services tab.
vCloud Air® Hybrid Cloud Manager™ Installation and Administration Guide
Page 22
3. Click Install service.
4. On the Choose Hybrid Services page, confirm the Organization Name and Virtual Data Center are correct. It should
be the organization you specified during the procedure to “Register the Hybrid Cloud Manager with a vCloud Air
Endpoint.”
Choose the services you want to install and click Next.
Configure the Hybrid Cloud Gateway
Follow the steps in, “Start Appliance Installation and Configuration” to open the installation Wizard and choose the
hybrid service appliance you want to install.
1. On the Hybrid Cloud Gateway page, provide the following values:
a. Network: The network where the Hybrid Cloud Gateway’s management interface is placed. This is usually a
port group on a particular switch. In use cases ❶ and ❷ it can be physical switch or a standard virtual
switch. For any configuration using L2 extension, it must be a virtual distributed switch (vDS).
b. Cluster/Host: Select the Cluster or Host where the Hybrid Cloud Gateway is deployed.
c. Datastore: Select the datastore where the Hybrid Cloud Gateway is deployed.
vCloud Air® Hybrid Cloud Manager™ Installation and Administration Guide
Page 23
d. VM/Hostname: This field is optional.
e. Provide the IP address, default gateway and DNS server to use for the Hybrid Cloud Gateway management
interface.
f. (Optional) Under Extended Configurations, set the admin and root passwords. These passwords are
specifically for the Hybrid Cloud Gateway appliance.
g. Click Next.
Configure the Network Extension Service
Follow the steps in, “Start Appliance Installation and Configuration,” and choose the Network Extensions service.
1. On the Network Extension Service page, choose a virtual distributed switch (vDS) from the Distributed Switch drop
down menu.
Choose the Route for Stretched Networks
• If you check “Route stretched networks via Hybrid Cloud Gateway,” the installer determines a reasonable
placement for the L2 Concentrator, based on the switch. The placement fields are not editable.
• If you do not check “Route stretched networks via Hybrid Cloud Gateway,” you must specify the Network,
Compute, and Datastore information for the L2 Concentrator.
Note: If you don’t use the Hybrid Cloud Gateway, you do not get the benefit of WAN optimization (if
installed) or intelligent routing.
i. Network: The network where the L2 Concentrator’s management interface is deployed.
vCloud Air® Hybrid Cloud Manager™ Installation and Administration Guide
Page 24
ii. Compute: Cluster or host where the L2 Concentrator is deployed.
iii. Datastore: Datastore where the L2 Concentrator is deployed.
Choose the L2 Network Parameters
• If you leave the option “Specify the Network Parameters for the local L2 Concentrator” unchecked, you will use
the default parameters provided by the installer.
• If you want to route directly over the internet, check “Specify the Network Parameters for the local L2
Concentrator,” and specify the connection parameters.
• If the port group you selected in the Hybrid Cloud Gateway page Network field (Step 1.a on page 20) is not part
of the distributed switch, check “Specify the Network Parameters for the local L2 Concentrator” so that you can
specify additional parameters for the local L2C.
When configuration is complete, click Next.
2. On the Ready to complete page, review the information, then click Finish.

viewing All Users’ Tasks. Click on More Tasks to open the Task Console. The network extension is done when the
Extend Network task status is Completed.
Migrating a Virtual Machine to vCloud Air
To migrate a virtual machine you must have a secure connection maintained by the Hybrid Cloud Gateway. You can
speed up the migration if you use a stretched network, Hybrid Networking Premium, WAN Optimization, a Direct
Connection, or a combination of these features.
Understanding Replication-Based Migration
Hybrid Cloud Manager enables bidirectional migration: on premises to the cloud, or from the cloud to back to on=premise datacenter. Hybrid Cloud Manager uses vSphere Replication during the migration process. vSphere Replication
is integrated in the Hybrid Cloud Gateway virtual appliance, so you don’t have to worry about installing or maintaining
vSphere Replication.
Note: Hybrid Cloud Manager uses vSphere Replication in the ESX hypervisor and Cloud Gateway. The
DRaaS replication appliance is not used.
Note: A migration cannot be cancelled once it is initiated.
To reduce downtime, the source VM remains online during the replication and is bootstrapped on the destination ESX
host once replication completes. The original virtual machine is copied to the “Migrated VMs” folder in the vSphere
Templates view to enable recovery.
A migration request from Hybrid Cloud Manager triggers the following actions:
1. Hybrid Cloud Manager uses vSphere Replication to create replication groups within the on-premises ESXi host
running the VM.
2. vSphere Replication begins a full synchronization transfer into a vCloud Air virtual datacenter (vDC).
The time it takes to replicate is a function of the size of the VM.
3. When full synchronization completes, a delta synchronization occurs.
4. When the delta synchronization is complete, Hybrid Cloud Manager executes a switchover. You can choose to start
immediately or delay the switchover until a specific time.
vCloud Air® Hybrid Cloud Manager™ Installation and Administration Guide
Page 30
5. Following the switchover, the source virtual is powered-off, and the migrated replica is powered on.
6. Hybrid Cloud Manager renames the powered-off replica to avoid a naming conflict with the live VM. A binary
timestamp is appended to the replica name.
The migration is complete, and conceptually, this is where replication stops.
• Powered off replicas are stored in your on-premises vCenter in folders named “VMs migrated from the cloud,”
and “VMs migrated to the cloud.”
• In this release, you must manually delete any unwanted replicas.
Checking Your VM before Migration
Before you migrate a VM, be sure that it meets these conditions.
• VM size must not exceed 62 TB.
• vSphere Replication can replicate virtual machines greater than 2TB with the following limitations:
• vSphere Replication tracks changed blocks, so the amount of data written to disk determines how much
memory is consumed.
• vSphere Replication tracks larger blocks on disks over 2TB. Replication performance on a disk over 2TB might be
different than replication performance on a disk under 2TB for the same workload depending on how much of
the disk goes over the network for a particular set of changed blocks.
• Replication bandwidth consumption varies depending on the workload and how it changes blocks on the disk
during the RPO interval.
• Hybrid Cloud Manager cannot migrate virtual machines that share VMDK files in this release.
• The VM must be powered on.
Migrating a Sample VM from an On-premises vCenter to the Cloud
The following procedure demonstrates how to migrate a workload VM from an on-premises datacenter to the vCloud
Air endpoint associated with the VM’s network. This sample migration uses two virtual machines in the vCenter where
Hybrid Cloud Manager resides. The sample VMs are:
• WordPress_App (192.168.200.200): Virtual Machine to be migrated to vCloud Air.
• eCommerce_App (192.168.200.201): Start a ping from this VM to the VM to be migrated.
If you want to follow along in your own environment, choose two VMs in the vCenter where the Hybrid Cloud Manager
resides. Migrate one VM, and use the other to track connectivity to the VM, as well as the overall progress of the
migration.
vCloud Air® Hybrid Cloud Manager™ Installation and Administration Guide
Page 31
1. On the Hosts and Clusters page, right-click the VM you want to migrate, and from the context menu, select Hybridity
Actions, and choose Migrate to vCloud Air.
2. In the Migrate Wizard on the “Select migration type” page, select an option that suits your purpose.
• Quick Switchover: Switch over as soon as the sync is ready.
• Scheduled Switchover: Switch over in a pre-determined maintenance window.
To duplicate the sample procedure, select the Replication based Migration with Quick Switchover option. Click Next.
3. On the “Selected virtual machine(s)” page, review the summary of the virtual machine you are migrating. Click Next.
vCloud Air® Hybrid Cloud Manager™ Installation and Administration Guide
Page 32
4. On the “Select destination page,” select the vCD Organization and vCloud Air virtual datacenter. Click Next.
5. On the “Select destination” network page, select the NSX Edge associated to the vCloud Air datacenter. Click Next.
• The Retain MAC box is checked by default if the VM is being migrated to a network that has been stretched. The
source (on-premises vCenter or vCloud Air vDC) does not matter. Checking this option minimizes network
downtime because the network does not have to relearn a new MAC address.
• The Retain MAC box is unchecked if the VM being migrated is not in a network that has been
stretched. Sometimes it is important to keep the same MAC address after the migration. We recommend
enabling Retain MAC in the following cases:
• License Based on MAC Address: some software pairs the license to the MAC address of the VM. Changing
the VM’s MAC address invalidates the license.
vCloud Air® Hybrid Cloud Manager™ Installation and Administration Guide
Page 33
• Linux NIC Order: In Linux, if you change the MAC address of a VM, the Ethernet device number of the NIC
may change after a reboot. This effectively changes the NIC order as it is presented within the operating
system, breaking scripts or software that depends on NIC order.
• If you uncheck Retain MAC a new MAC address is obtained when the VM migration is complete.
6. On the Select storage tier, confirm the selection and click Next.
7. On the Ready to complete page, review the selections and click Finish to start the virtual machine migration.
8. You can monitor the migration progress in several ways.
a. Tasks Console: In the Recent Tasks window, click the All tab and ensure you are viewing All Users’ Tasks. Click
on More Tasks (marked in red on the lower right in the following screen shot), and in the task console, watch
the Migrate VM task. When the status is Completed, the VM has been migrated and powered on in vCloud Air.
vCloud Air® Hybrid Cloud Manager™ Installation and Administration Guide
Page 34
b. CLI: Log in to the ESXi host running the virtual machine using SSH.
Run this command to obtain the virtual machine ID:
# vim-cmd vmsvc/getallvms | grep -i vmname
Vmid Name File Guest OS Version
6 WordPress_App [storage]WordPress_App/WordPress_App.vmx otherLinuxGuest vmx-10
Run these commands to monitor replication state using the Vmid obtained in the previous step:
# vim-cmd hbrsvc/vmreplica.getState vmid
# vim-cmd hbrsvc/vmreplica.queryReplicationState vmid
c. ICMP Ping: Monitor the continuous ping you started earlier.
The test ping should resume shortly after the Migrate VM task is completed.
9. After the migration, view the vCenter and note the folders labeled “VMs migrated from the cloud,” and “VMs
migrated to the cloud.”
• As discussed in “Understanding Replication-Based Migration,” the powered on VM has its original name. Any
replicas have a binary timestamp appended.
• Replica VMs can be used like any other VM.
Note the live and replica VMs in the following screen shot. The VM vcc-cm5 has been migrated back and forth
several times.

Unstretching an L2 Network
This procedure unstretches a stretched Layer 2 network. This task is necessary if you want to remove the L2C service
appliance, or if you want to completely uninstall Hybrid Cloud Manager.
1. Check Stretched Networks:
From the Hybrid Cloud Manager plugin page, view the Extended Networks page. If there are active jobs, wait until
they are complete.
2. Log in to the vSphere Web Client and click on Hosts and Clusters.
3. Click on the Networking tab. From the Networking section, identify the port group for the network you want to
unstretch.
4. Right-click the port group, and from the submenu, select Hybridity Actions, and then choose Unstretch Network.
Removing Hybrid Service Appliances
You might want to remove one of the service appliances if you change your mind about your installation architecture, or
if you are preparing to remove Hybrid Cloud Manager.
Never delete virtual appliances from the vSphere inventory. Use the Hybrid Cloud Manager to administer the appliances.
The virtual appliances must be in the inactive state when they are removed.
1. Check the vSphere Web Client task console for any running migrations, and wait until they are complete. See
“Migrating a Sample VM from a vCenter to the Cloud,” Step 14.
2. If you are using the Layer 2 extension, follow the steps in, “Unstretching an L2 Network” for all stretched networks,
then continue to Step 3.
3. Ensure there are no active Hybrid Cloud Manager jobs of any type.
4. In the vSphere Web Client interface, select the Hybrid Cloud Manager plugin in the left-hand panel.
5. Click Administration (in the left-hand panel), and click the Hybrid Cloud Service Configuration option. A list of the
installed appliances is displayed in the right-hand pane.
6. Locate the Hybrid Cloud Gateway appliance and click the entry to show the details.
Note: The Hybrid Cloud Gateway must be in the inactive state. If necessary, deactivate the
appliance.
7. Click the X icon to remove the appliance (the Remove button is on the lower right).
Hybrid service appliances that use the Hybrid Cloud Gateway are removed from both the vCenter and the vCloud Air
vDC.
Note: If you stretched a network but did not route the network through the Hybrid Cloud Gateway,
the L2 Concentrator won’t be automatically removed when the Hybrid Cloud Gateway is
removed. Expand the appliance details, and click the X icon to remove the L2 Concentrator.
Troubleshooting
This section provides workarounds for features that are not performing as designed, and also discusses some possible
configuration changes to address performance issues.
vCloud Air® Hybrid Cloud Manager™ Installation and Administration Guide
Page 37
Resetting the MAC Address
You can edit the MAC settings after migration completes.
1. From the vSphere client, power off the virtual machine.
2. Open the VM in the vSphere Web Client and click Edit Setting.
3. Change Network Adapter MAC Address to “Manual” and enter the desired MAC address.
High Host Resource Consumption
In rare cases the Hybrid Cloud Manager VMs can exhaust a host’s CPU and disk resources. Some users have seen this
when all virtual appliances were installed on one physical host (by choice, or perhaps there was only one host with 12+
GB RAM at the time of installation). Given this configuration, performance is affected when the following things happen
concurrently:
• The network has high latency and/or packet loss -- most likely when migration or data transport is slow because you
are using a busy network or the public internet
• The WAN Optimizer is consuming bandwidth to encrypt and compress (or decrypt/uncompress) large workloads
• There is high application traffic between on-premises VMs and migrated VMs
If you are running out of resources, please contact VMware Global Support Services (GSS):
https://my.vmware.com/group/vmware/contact-vmware
Please communicate your requirements to GSS. They can work with you to reconfigure your environment with a
minimum amount of downtime. Although you can move resources in your vCenter, you should not do so. Only GSS can
reconcile the change in the vCloud Air vDC.
