HP Integrity Virtual Machines Installation, Configuration, and Administration

10 Migrating Virtual Machines
The hpvmmigrate command allows you to move a virtual machine from a source VM Host
system to a destination VM Host system. The hpvmmigrate command is available with HP
Integrity Virtual Machines A.01.20 and later. For information about installing the optional
VMMigrate bundle, which provides the hpvmmigrate command, see “Installing Integrity VM”
(page 21).

10.1 Introduction to Virtual Machine Migration
Virtual machines can be moved from one VM Host system to another in a variety of ways.
Integrity VM provides the following types of virtual machine migration:
• To move the virtual machine from one VM Host system to another, use the hpvmmigrate
command Optionally, you can modify the virtual machine characteristics and resources at
the same time. For example, use this method if the new VM Host has different resources
from the old VM Host. For more information, see Section 10.2: “Migration Guests from VM
Host to VM Host” (page 132).
• To move the virtual machine from one system to another, use the p2vassist utility. For
example, use this method to move virtual machines from a partition or a system to a VM
Host system. Guests must be shut down before the procedure and restarted after the
migration. For more information, see Section 10.4: “Migrating Guests from Physical to Virtual
Machines” (page 135).
Figure 10-1 illustrates the process of moving a guest from Host A to Host B.
