HP Integrity Virtual Machines 4.3: Installation, Configuration, Administration

CAUTION: HP does not recommend using the -x register_status option. Integrity VM
commands ensure that the VM is registered only on one VM Host at a time. Registering a VM
on more than one VM Host can lead to accidentally booting the VM on more than one VM Host
and could cause inconsistencies with the display of graphical tools. However, if you find that
VM is not registered on any VM Host, you can manually register it with the hpvmmodify
command. For information on this command, see Section 9.1.3.
8.2.3 Changes to the hpvmmodify Command
The hpvmmodify -x command has been changed to allow changing the modify_status,
and visible_status, and register_status attributes with the -x option, in addition to
runnable_status.
# hpvmmodify -P vmname -x runnable_status={enabled|disabled}
# hpvmmodify -P vmname -x modify_status={enabled|disabled}
# hpvmmodify -P vmname -x visible_status={enabled|disabled}
# hpvmmodify -P vmname -x register_status={enabled|disabled}
• The runnable_status option, which already exists in Integrity VM, prevents a VM from
being started.
CAUTION: HP does not recommend using the -x runnable_status option. Integrity
VM ensures that the VM is runnable only on one VM Host at a time. Marking a VM runnable
on more than one VM Host can lead to accidentally booting the VM on more than one VM
Host.
• The modify_status option of a VM is listed in the hpvmstatus -V output. If
modify_status=disabled, you cannot modify a VM except to set
modify_status=enabled.
CAUTION: HP does not recommend using the -x modify_status option, except with
extreme caution. If modify_status is disabled, the VM is most likely running on another
VM Host. Any modification made to this VM's configuration will be lost when it is migrated
back to this VM Host.
• You can enable or disable visible_status with the hpvmmodify command. When a VM
has the visible_status option set to disabled, the graphical tools will not display the
VM.
CAUTION: HP does not recommend using the -x visible_status option, except with
extreme caution. Use of this option may cause inconsistencies with the display of graphical
tools and has no effect on the command-line output.
• If a VM is not registered on any VM Host, you can manually register it with the hpvmmodify
-x register_status=enabled command.
CAUTION: HP does not recommend using the -x register_status option. Integrity
VM commands ensure that the VM is registered only on one VM Host at a time. Registering
a VM on more than one VM Host can lead to accidentally booting the VM on more than one
VM Host, which could cause inconsistencies with the display of graphical tools.
The hpvmmodify command does not allow modification to guests marked
modify_status=disabled. When the modify_status=disabled attribute is set, the only
change allowed is to set the modify_status=enabled attribute. When the hpvmmigrate
command sets the guest to the NR state (runnable_status=disabled), it now also sets the
modify_status=disabled and visible_status=disabled attributes. Likewise, when
