HP Integrity Virtual Machines 4.2: Installation, Configuration, and Administration
hpvmmodify command, if necessary, to mark the guest Runnable on only one single VM Host,
and Not Runnable on all other VM Hosts that have the virtual machine configured.
When hpvmmigrate sets the guest to Not Runnable state (runnable_status=disabled)
, it also sets modify_status=disabled and visible_status=disabled. Likewise, when
hpvmmigrate sets the guest to a Runnable state, it also sets modify_status=enabled and
visible_status=enabled.
NOTE: Mark a migrated guest as Runnable only in rare circumstances and with great care.
Inappropriate use can cause disk corruption if a guest is booted on more than one host at the
same time.
If you migrate a virtual machine that is being managed by ID-VSE, use Capacity Advisor to
collect utilization data before you migrate the virtual machine. Otherwise, the utilization
information for the VM Host prior to the migration is lost.
Cloning or modifying a guest during online migration is not allowed.
Online migration of a guest from a V4.2 VM Host back to a V4.1 VM Host is not supported with
one exception. If a guest was originally booted on a V4.1 VM Host and then migrated online to
a V4.2 VM Host, you can perform an online migrate on that guest back to a V4.1 VM Host.
Options
The hpvmmigrate command recognizes the following command-line options and arguments:
-A
Aborts an active guest migration.
-b For offline migrations, causes the hpvmmigrate command
to boot the virtual machine on the target automatically
after the migration process is complete. If the -b option is
specified for an offline migration, all backing stores must
exist or must be copied.
-c number-vcpus
For offline migrations, specifies the number of virtual CPUs
this virtual machine sees at boot time.
-C
For offline migrations, physically copies the single storage
device specified with the -m option to the target VM Host
during the migration process. If specified before the first
-m option, it applies to all -m options that specify an
appropriate type of storage. This might take a long time
to complete if a large amount of storage needs to be copied.
-d For offline migrations, causes hpvmmigrate to
automatically shut down a running guest before migrating
the guest to the target VM Host. Consider migrating the
guest online by using the -o option.
-D
Deletes the virtual machine from the source VM host after
migrating the virtual machine to the target VM Host. If not
specified, the virtual machine is marked Not Runnable
on the source VM Host after migration.
-e percent[:max-percent]
For offline migrations, specifies the percentage of CPU
resources to which each of the virtual machine's virtual
CPUs is entitled.
During peak system CPU load, the entitlement is the
guaranteed minimum allocation of CPU resources for this
virtual machine.
The percent can be set to an integral value between 0 and
100. If the value specified is less than 5, the virtual machine
