HP-UX vPars and Integrity VM V6.3 Administrator Guide

The virtual iLO Remote Console uses the SSH server host keys of the host system. If the guest
is migrated to another host system (using OVMM), these host keys change. When an end user
does an SSH connection, an error message is displayed. The end user must manually delete
the local copy of the host key. For additional information, see ssh(1).
• Guest Administrator accounts are not migrated during OVMM.
Guest administrator accounts on the source VSP system are not automatically migrated to the
target VSP system during OVMM. You must manually add guest administrator accounts to the
target VSP system, using the same useradd commands that are used on the source system.
For information about creating Guest Administrator and Operator accounts, see Section 13.10
(page 225).
• The virtual iLO Remote Console does not support rlogin connections.
13.13 Guest configuration files
When the guest is created, the VSP 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 guest configuration that is 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.
CAUTION: 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.
13.14 Managing dynamic memory from the VSP
On the VSP, the dynamic memory feature is included with Integrity VM. You can manage dynamic
memory on the VSP 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. Table 32 (page 232) lists the -x keywords
used for dynamic memory.
