HP Integrity Virtual Machines 4.3: Installation, Configuration, Administration

NOTE: When assigning a null device to a resource on a
virtual machine, the file name serves as a placeholder.
Therefore, if the file does not exist, you do not receive an
error. For example, in the following command, if the file
XXX.iso does not exist, no error is given.
# hpvmmodify -P vm1 -a
disk:scsi::null:/opt/XXX.iso
The resource is specified as described in hpvmresources(5).
This option can be specified more than once.
-d rsrc
Deletes an I/O resource from a virtual machine. The
resource is specified as described in hpvmresources(5). The
physical device portion of the rsrc is optional.
This option can be specified more than once.
-m rsrc
Modifies an existing I/O resource for a virtual machine.
The resource is specified as described in hpvmresources(5).
You must specify the hardware address of the device to
modify. The physical device portion of the rsrc specifies
a new physical device to replace the one in use. To move
from VIO to AVIO, use the following command:
# hpvmmodify -P guest1 -m hba:avio_stor:0,5
This option can be specified more than once.
The rsrc specifies the mapping of a guest virtual device
to a VM Host backing store. Integrity VM guests access
virtual devices that are instantiated on physical entities
managed by the VM Host. These physical entities (for
example, network cards, files, logical volumes, and so forth)
are collectively referred to as backing stores.
Integrity VM recognizes the following types of guest virtual
devices:
• Virtual disks, which can be backed by files in a VM
Host file system, by logical volumes or by whole disks.
• Virtual DVDs, which can be backed by files in a VM
Host file system or by the physical DVD drive.
• Virtual network devices, which are created through
the hpvmnet command and backed by physical LAN
cards. For more information about virtual network
devices, see hpvmnet(1M).
For information about specifying storage and network
resources for guests, see the hpvmresources manpage.
Integrity VM Version 4.3 supports the usage of both legacy
and agile devices in guest configurations. Over time, you
should migrate from using legacy device names to agile
device names to simplify the management of devices. You
can use the hpvmmodify -P guest -m rsrc command
to change the existing legacy device to its agile device
equivalent. The ioscan -m dsk command displays the
mapping of the agile devices to legacy devices for the
specific device special file, dsf.
