Migrating a Domain

3.Mount the shared virtual disk: mount /OVS/remote

6.2Migrating a Domain

To migrate a domain from one computer to another identical computer:

1.Create a shared virtual disk to use during the domain migration. See Section 6.1, "Creating a Shared Virtual Disk for Live Migration". Each computer involved with the domain migration must have access to the shared virtual disk in the same way, either as an NFS or a SAN virtual disk.

2.On the Oracle VM Server that contains the existing domain, migrate the domain to to the remote computer with the following command:

xm migrate mydomain myremotecomputer

The domain is migrated to the remote computer.
