3.2.12 Sizing Guidelines

The sizing guidelines for Integrity Virtual Machines Version 4.0 and later are different from that

of previous releases due to several factors, including the change of VM Host operating system

to HP-UX 11i v3. As a result, the formulas used to calculate virtual machine 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 from:

3.2.13 Default Guest Settings for HP-UX and OpenVMS

Table 3-4 lists the default guest settings for HP-UX, OpenVMS and Unknown guests. An Unknown

guest is a virtual machine 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 operating system type

with the -0 option to the hpvmcreate command.
