Table 3-7 Options to the hpvmmodify Command (continued)

DescriptionOption

Specifies whether the virtual machine is managed by Serviceguard or gWLM

(or both). For the argument, specify one or more of the following parameters:

• SG indicates that the VM Host is a Serviceguard cluster node.

• SG-pkgname indicates that the VM Host is a Serviceguard package.

• GWLM indicates that the VM Host is managed by gWLM.

• NONE indicates there are no external managers.

For a node that is managed by both Serviceguard and gWLM, parameters are

separated with a comma. For example: SG_host1,gWLM. Do not specify this

option. This option is used internally by Integrity VM.

-i package-name

Specifies whether the virtual machine is a distributed guest (that is, managed

by Serviceguard) and can be failed over to another cluster member running

Integrity VM. Do not specify this option. This option is used internally by

Integrity VM.

-j [0|1]

Specifies values for dynamic memory setting associated with the guest,

including:

• dynamic_memory_control

• ram_dyn_type

• ram_dyn_min

• ram_dyn_max

• ram_dyn_target_start

• ram_dyn_entitlement=amount

• amr_enable={0|1}

• amr_chunk_size=amount

• runnable_status

• not_runnable_reason

• graceful_stop_timeout

• sched_preference

Specifies settings for Online VM Migration:

• online_migration

• migrate_init_phase_timeout

• migrate_copy_phase_timeout

• migrate_io_quiesce_phase_timeout

• migrate_frozen_phase_timeout

• online_migration

For more information about dynamic memory, see Section 9.7 (page 151).

-x keyword=parameter

For example, to modify the characteristics of the problematic virtual machine host1 to remove

vCPUs and memory, enter the following command:

# hpvmmodify -P host1 -c 1 -r 2G

This command changes the following characteristics of the virtual machine named host1:

• The -c 1 option specifies one vCPU.

• The -r 2G option specifies two GB of memory.

The hpvmmodify command generated no warnings, so the VM Host system is ready to start the

virtual machine.

After you make the necessary modifications, use the hpvmstart command to start the virtual

machine. For example:

# hpvmstart -P host1
