Domain Live Migration 6-1
6Domain Live Migration
This Chapter discusses live migration of domains to other, identical computers. You
must use identical computers to perform live migrations, that is, the computer make
and model number must be identical.
To perform live migration of domains, you must create a shared virtual disk before
you perform the migration. This Chapter contains:
■ Creating a Shared Virtual Disk for Live Migration
■ Migrating a Domain
6.1 Creating a Shared Virtual Disk for Live Migration
If you want to perform live migration of domains to other, identical, computers, you
must create a shared virtual disk to be used during the live migration. You can set up a
shared virtual disk in the following configurations:
■ OCFS2 (Oracle Cluster File System) using the iSCSI (Internet SCSI) network
protocol
■ OCFS2 using SAN (Storage Area Network)
■ NFS (Network File System)
You must make sure all Virtual Machine Servers in the server pool:
■ Use the same shared storage.
■ Are in the same OCFS2 or NFS cluster.
This section discusses creating a shared virtual disk to use for live migration.
6.1.1 Creating a Shared Virtual Disk Using OCFS2 on iSCSI
To create a shared virtual disk using OCFS2 on iSCSI:
1. Install the iscsi-initiator-utils RPM on the Oracle VM Server. The
iscsi-initiator-utils RPM is available on the Oracle VM Server CDROM or ISO file.
# rpm -Uvh iscsi-initiator-utils-version.el5.i386.rpm
2. Start the iSCSI service:
# service iscsi start
3. Run discovery on the iSCSI target. In this example, the target is 10.1.1.1:
# iscsiadm -m discovery -t sendtargets -p 10.1.1.1
