HP Integrity Virtual Machines Release Notes

3 Creating Virtual Machines
This section contains notes about creating and configuring virtual machines on the VM Host
system.
3.1 Default Guest Settings for HP-UX, Windows, and Linux
Table 3-1 lists the default guest settings for HP-UX, Windows, Linux, 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.

NOTE: The amount of memory you should allocate to the guest must be sufficient to allow the
guest operating system to boot. This amount may differ from the defaults documented here.
Refer to the product documentation for the operating system and applications on the guest for
specific memory requirements.
3.2 Autoboot Causes Virtual Machines to Start
The virtual machine start_attr attribute can be set to auto or manual using the —b option
to the hpvmcreate, hpvmmodify, and hpvmclone commands. When this attribute is set to
auto, the virtual machine starts whenever Integrity VM starts running. This also occurs after
you install or upgrade Integrity VM.
3.3 Reserving Swap Space for Guests
Integrity VM installation requirements includes swap space for guests. Swap space on the VM
Host must be configured as device swap (not file system swap). The amount of swap space must
be no less than the total size of physical memory plus 4 Gb.
The VM Host uses this space to start up guests, but guests are never swapped out. (A guest's
physical memory is locked down.) By turning off the swapmemon feature on the VM Host,
Integrity VM conserves RAM for guest use.
