HP Integrity Virtual Machines Installation, Configuration, and Administration Version A.03.50

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.
This chapter includes the following sections:
• Section 10.1: “Introduction to Virtual Machine Migration” (page 143)
• Section 10.2: “Migration Guests from VM Host to VM Host” (page 144)
• Section 10.3: “Network and Storage Migration Considerations” (page 146)
• Section 10.4: “Migrating Guests from Physical to Virtual Machines” (page 147)
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 (page 144).
• 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 (page 147).
Figure 10-1 illustrates the process of moving a guest from Host A to Host B.

The basic virtual machine migration configuration includes a source machine and a target machine.
Both must be running Integrity VM and must be able to run the guests. Both machines must
conform to their operating system requirements and restrictions, and both must be able to provide
