Changing Guest Configurations

To modify the resources of a guest, use the hpvmmodify command. For example, guest compass1 cannot start. The following message is generated:

# hpvmstart -Pcompass1
HPVM guest compass1 configuration problems:
Warning 1: Insufficient free memory for guest.
Warning 2: Insufficient cpu resource for guest.
   These problems may prevent HPVM guest compass1 from booting.
hpvmstart: Unable to continue.
#

To modify the configuration of the problematic guest compass1 to remove virtual CPUs and memory, enter the following command:

# hpvmmodify -Pcompass3 -c1 -r1GB
# hpvmstart -Pcompass1

When the guest is created, the VM Host creates the guest configuration file /var/opt/hpvm/guests/guestname.

Integrity VM creates up to three guest configuration files:

vmm_config.current contains the current guest configuration currently set.
vmm_config.prev contains the last known guest configuration settings.
vmm_config.next contains the configuration settings that have changed since the guest was started. To initiate these changes, you must reboot the guest.
