HP-UX vPars and Integrity VM V6.3 Administrator Guide

9.1.9 Sizing guidelines
The sizing guidelines for Integrity VMs Version 4.0 and later are different from that of earlier
releases due to several factors, including the change of VSP operating system to HP-UX 11i v3.
The formulas used to calculate VM capacity are outlined in the white paper Hardware Consolidation
with Integrity Virtual Machines. The sizing information and related calculations are updated in
revisions to this white paper dated September 2008 or later. The latest version of this white paper
is available at: http://www.hp.com/go/virtualization-manuals.
9.1.10 Default guest settings for HP-UX
Table 19 (page 138) lists the default guest settings for HP-UX and Unknown guests. An Unknown
guest is a VM that has not booted with any operating system. When an Unknown guest type boots,
the appropriate operating system type is applied to the guest configuration.
The following guest OS specific settings are applied if you specify the -o option for the operating
system type in the hpvmcreate command.

The minimum memory requirement for HP-UX 11i v2 is 512 MB. The minimum memory requirement for HP-UX 11i v3 is
1 GB (see "System Requirements" section in the HP-UX 11i v3 Installation and Update Guide); however, the HP-UX 11i
v3 Installation and Update Guide warns that cold installations with 1 GB or less memory might fail or take a long time
to complete. Therefore, HP recommends 2 GB for cold installations of HP-UX 11i v3.
NOTE: The amount of memory you must allocate to the guest must be sufficient to allow the guest
operating system to boot. This amount might differ from the defaults documented here. For specific
memory requirements, see the documentation for the operating system and applications on the
guest.
9.2 Using the hpvmcreate command
To create a VM, run the hpvmcreate command. Enter the -P option to specify the VM name (up
to 255 alphanumeric characters). All other options are optional and might be added to the VM
configuration later using the hpvmmodify command.
Table 20 (page 139) lists the options that can be used with the hpvmcreate command.
