Implementing Live Migration for virtual machine availability

A VM guest can be migrated from one host to another host. This migration can be a live migration or pause migration. You can initiate the migration using either the virsh migrate command or using virt-manager console. Veritas Cluster Server (VCS) monitors the migrated guest and can detect the migration process. VCS changes the resource state according to the state, i.e. if the guest is live-migrated from one host to another host, the associated KVMGuest resource is brought online on the host where the guest is migrated. VCS does not initiate the VM guest migration. Sample Configuration Symantec recommends the use of CVM-CFS in case of VM guest migration for storing the guest image.

See Sample configuration.
