Installing and configuring Cluster Server for Oracle Virtual Machine (OVM) virtual-to-virtual clustering
Oracle VM is an enterprise-grade server virtualization solution that supports guest (virtual machines) that supports various operating systems, including Linux. Based on the Xen hypervisor technology, OVM also provides you with an integrated, Web-based management console.
Before you install VCS on the guest virtual machines, you must set up a private network between them. This involves the following steps:
To enable VCS support of virtual-to-virtual clustering
- Set up a private network between the guest virtual machines.
Apart from the public NIC on each physical host, create two additional NICs.
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.
If the virtual machines for which you configure the network run on separate physical hosts, ensure that you create a LLT communication channel between the physical hosts.
Attach a switch to each of the two additional NICs
To create a private network on the physical host
- From the Oracle VM 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 virtual machines
- Create two interfaces (in a network that is created with the option Create a hybrid network with bonds/ports and VLANS) and associate the interfaces with the newly-created virtual networks.
- Repeat step 1 for each virtual machine where you want to monitor availability with VCS.
To set up a cluster of virtual (guest) machines with Cluster Server (VCS), perform the following procedures:
Consult the requirements in:

Configure VCS in the guest virtual machine
Cluster Server Configuration and Upgrade Guide
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.
Veritas has supported live migration in the OVM environment under the following conditions:
Virtual machine image resides on NFS data domains
VCS supports non-SCSI3, CP server-based fencing in virtual machines to prevent corruption of data disks.
For information on configuring fencing, see the Cluster Server Configuration and Upgrade Guide.
