Using AVIO with Integrity VM

AVIO is supported on HPV-UX 11i v2 guests and is optional based on a properly configured VM Host and changes to the guest configuration. You must install and configure kernel drivers on both the VM Host and the guest systems. AVIO supported guests are HP-UX 11i v2 (0505 or later). The guest configuration file and the hpvmstatus command display the avio_lan and avio_stor designators. The following example shows the hpvmstatus command output of AVIO adapters for guest avioclone:

	NOTE: The command line interface (CLI) accepts either avio_lan or aviolan and either avio_stor or aviostor. For example, the following hpvmcreate commands add both an AVIO network and an AVIO disk to the guest aviotest: # hpvmcreate -P aviotest -O hpux -a network:aviolan::vswitch:swlan1 \ -a disk:aviostor::disk/dev/rdsk/clt2d0 # hpvmcreate -P aviotest -O hpux -a network:avio_lan::vswitch:swlan1 \ -a disk:avio_stor::disk/dev/rdsk/clt2d0

The AVIO network host driver allows simultaneous access to a vswitch from guests configured with or without AVIO guest drivers for their virtual network interface cards (vNICs). Existing guests continue to operate correctly and their configurations remain unchanged. Guests configured to use a common vswitch are allowed to share VLANs that are in use by guests with or without AVIO configured. Ports remain distinct for each running guest whether or not AVIO is in use. AVIO networks must use a Supported Host Physical Point Attachment (PPA) network device. For a list of supported AVIO PPAs, see Section . A nonphysical vswitch, such as localnet, is not supported in this release.

The AVIO storage host driver allows access to an Integrity VM Host backing disk as long as all sharing guests are configured to use AVIO. In this release, AVIO supports the disk and DVD device types, while burner, tape, and changer device types are not supported. The dynamic addition and deletion of AVIO devices is supported. The supported backing store options are:

All other backing store options, such as file, null (for non-DVD devices), and attached, are not supported.

	NOTE: In general, AVIO devices (that is, avio_lan, aviolan, avio_stor, or aviostor) are configured and managed the same as VIO devices (that is lan and scsi). However, there are some additional Integrity VM command options and limitations on backing devices that are noted throughout this document.
