HP Integrity Virtual Machines 4.3: Installation, Configuration, Administration

Table 9-3 Options to the hpvmmigrate Command (continued)
DescriptionOption
For offline migrations, physically copies the 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.
-C
For offline migrations, causes hpvmmigrate to automatically shut
down a running guest before migrating the virtual machine
configuration to the target VM Host. Consider migrating the guest online
by using the -o option instead.
-d
Deletes the virtual machine from the source VM Host after migrating
the virtual machine to the target VM Host system. If not specified, the
virtual machine is marked Not Runnable on the source VM Host after
migration.
-D
For offline migrations, specifies the percentage of CPU resources to
which each of the virtual machines 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 is allocated the minimum percentage
of 5%. The default is 10%. Integrity VM reserves processing power for
essential system functions such as logging, networking, and file system
daemons. The -e and the -E options are mutually exclusive.
-e [:max-percent ]
For offline migrations, specifies the virtual machine's CPU entitlement
in CPU cycles. The cycles are expressed as an integer followed by one
of these units:
• M (megahertz)
• G (gigahertz)
If no letter is specified, the default unit is megahertz. The -e and the
-E options are mutually exclusive.
-E [:max-cycles]
Forces the migration of a virtual machine, whether or not there are
resource validation errors (such as resource conflict, resource
nonexistence, and so forth). . Use the -F option rarely and with caution.
This option ignores all resource validation errors, including
oversubscribing of resources.
NOTE: These errors can prevent the virtual machine from booting on
the target VM Host. Any validation errors are logged in the Integrity
VM command log.
The -Foption is deprecated in Integrity VM commands; this option
should be used only at the direction of HP Support
-F
Specifies the host alias or IP address of the target VM Host machine to
which the virtual machine is being migrated. The target machine must
be a valid VM Host and must be accessible by the source VM Host.
Almost all forms of the hpvmmigrate command require the -h option.
For online migration, the parameter for the -h option should specify a
private, dedicated, high-speed network link to the target VM Host.
If you specify a simple non-qualified host name, the hpvmmigrate
command appends -hpvm-migr to the name and checks if a host alias
has been defined for a private network corresponding to the simple
name. Online guest migration does not check to ensure the link is
private, but using a private network is important for efficient and secure
online migrations and to preserve the bandwidth of the regular site
network.
