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. Table 3-1 Guest Default Settings HP-UX Guest Default Windows Guest Settings Default Settings Maximum CPUs Default CPUs Default memory Minimum memory Maximum memory Default reserved memory Minimum reserved memory Maximum reserved memory 4 1 2 GB 512 MB 64 GB 64 MB 32 MB 64 GB 4 1 2 GB 32 MB 64 GB 64 MB 64 MB 64 GB Linux Guest Default Settings 4 1 2 GB 512 MB 64 GB 64 MB Unknown Guest Operating System Default Settings 4 1 2 GB 32 MB 128 GB 64 MB 32 MB 32 MB 64GB 128 GB 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. 3.1 Default Guest Settings for HP-UX, Windows, and Linux 25
