HP Integrity Virtual Machines 4.2: Installation, Configuration, and Administration

synchronization is strongly recommended on all VM Hosts and guests to maintain consistent
time accuracy.
10.3.1 VM Host Requirements and Setup
The VM Hosts must be configured with Integrity VM Version 4.2 or later. All the latest HP-UX
patches required by Integrity VM, as well as any required Integrity VM patches for Integrity
VM, should be installed. Consult the most recent HP Integrity Virtual Machines Release Notes,
available from http://docs.hp.com/en/vse.html, for general Integrity VM installation details,
including supported VM Host operating system versions, patches, and other system requirements.
Required patches are available on the http://www.itrc.hp.com website.
10.3.1.1 VM Host Processors for Online Migration
VM Hosts can be different Integrity server models with different numbers of processors, different
I/O adapters and configurations, different amounts of memory, different firmware revisions,
and so on. In particular, guests can migrate between radically different size, capacity, and power
VM Hosts. However, for online migration, all the eligible VM Host servers in a group must have
equivalent architecture implementations. They must all report the same processor family output
for the HP-UX command machinfo -v. Different processor frequencies and cache sizes are
supported for Online VM Migration. Table 10-2 lists the recent Itanium processors showing
different values for processor family:

Look for identical processor Family as shown in the following example output from the
machinfo -v command. (As more processors families and models are added, more specific
capability requirements might be necessary.) The systems host19 and host20 in this example
are compatible for migration, because they have the same processor family (32).
