The Microsoft Hyper-V role is a hypervisor-based server virtualization technology for the x86_64 architecture. It provides you with the software infrastructure and management tools that you can use to create and manage a virtualized server computing environment.

To enable VCS support for in-guest clustering, before you install VCS on the guest virtual machines, you must set up a private network between them. This involves the following steps:

Add two NICs to the virtual machine for private communication

Note:

Veritas recommends that you add one more interface/NIC to the virtual machine for public communication. Also, if the virtual machines for which you are configuring the network run on separate physical hosts, ensure that you set up an LLT communication channel between the physical hosts.

Attach a switch to each of the two additional NICs

To create a virtual network on the physical host

From the Hyper-V manager, create two virtual networks for private LLT heartbeat communication.
Assign appropriate physical interfaces to the newly-created virtual networks.

To configure the network for the virtual machines

Create two network interfaces of 'Legacy Network Adaptor' type, and associate them with the newly-created virtual networks.
Repeat step 1 for each virtual machine where you want to monitor application availability with VCS.

To set up a cluster of virtual (guest) machines with Cluster Server (VCS), perform the following procedures:

Note:

The installation and configuration of VCS inside a virtual machine is similar to that of the physical system. No additional VCS configuration is required to make it work inside the virtual machine.

For more details, see the Cluster Server Administrator's Guide.

Fencing support for VCS in-guest clusters

VCS supports non-SCSI3, CP server-based fencing in virtual machines to prevent corruption of data disks. SCSI3 fencing is not supported.

For information on configuring fencing, see the Veritas InfoScale Installation Guide.

Live migration support

VCS in-guest clustering continues to provide high availability of applications on virtual machines, in live migration scenarios initiated by the virtualization technology.

Veritas has tested for live migration support in the Hyper-V environment under the following conditions:

Microsoft Failover Clustering is enabled
Virtual machine image resides on Microsoft Clustered Shared Volumes
