9.5 Guest Configuration Files
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:
• The vmm_config.current file contains the current guest configuration currently set.
• The vmm_config.prev file contains the last known guest configuration settings.
• The vmm_config.next file contains the configuration settings that have changed since the
guest was started. To initiate these changes, you must reboot the guest.
Never modify the guest configuration files manually. Always use the appropriate Integrity VM
command (hpvmmodify or hpvmdevmgmt) to modify guest configuration parameters. Directly
modifying the guest configuration files can cause guests to fail in unexpected ways.
9.6 Dynamic Memory
Dynamic memory is an optional feature of Integrity VM that allows you to change the amount of
physical memory in use by a virtual machine without rebooting the virtual machine. In this
release of Integrity VM, dynamic memory is available on HP-UX guests only.
An example of this feature allows a guest that is a Serviceguard node to be used as a standby
server for multiple Serviceguard packages. When a package fails over to the guest, the guest
memory can be changed to suit the requirements of the package before, during, and after the
failover process.
To use dynamic memory, the guest must have the guest management software installed, as
described in Section 4.2 (page 54).
9.6.1 Managing Dynamic Memory from the VM Host
On the VM Host, the dynamic memory software is included with Integrity VM. Manage dynamic
memory on the VM Host using the -x option with the hpvmcreate, hpvmmodify, or hpvmclone
command. The -x option associates a variety of configuration parameters with the guest, including
dynamic memory and network management for the guests. For a complete list of -x keywords
used for dynamic memory, see Table 9-3.
