The live migration prerequisites include the following:
Both servers are installed with OpenSolaris 2009.06 x86.
■
Both servers are able to access the Internet to enable the downloading of
OpenSolaris packages.
■
Both the source server and the target server are on the same subnet.
■
The source and the target x86 servers have the same CPU model and type.
■
Both servers are running the same release of the xVM hypervisor software,
which means they must have the same version of OpenSolaris—in our case,
2009.06.
■
Sufficient CPU and memory resources exist on the target server to host the
migrating guest domain.
■
The target dom0 has the same network interface as the source dom0 network
interface used by the guest domain. For example, if the guest domain to be
migrated has a Virtual Network Interface (VNIC) that is bridged over the
e1000g0 interface on the source dom0, then the target dom0 must also have
the e1000g0 interface.
■
The source and target servers are both able to access a shared NFS resource
on a single subnet.
■
The following steps should be performed on both servers.
1. Create and mount a new boot environment.
#
/usr/sbin/beadm create -a -d 'xVM hypervisor' xvm
#
/usr/sbin/beadm mount xvm /mnt/xvm
#
/usr/sbin/beadm list
