HP Integrity Virtual Machines Version 4.2 Release Notes

9 Migrating Virtual Machines
This chapter contains information about migrating virtual machines.
9.1 Changes and Issues in This Release
The following section provides updated information about online migration in the V4.2 release.
9.1.1 Online Migration Support Limited to System with Compatible Processors
Online migration support among Integrity servers is limited by the processor architecture. Online
migration among servers with processor family 31 is supported regardless of the model number
within that family. Only migration among servers with processor family 32 and model numbers
0 or 1 is supported. Otherwise, online migration is supported only among servers with identical
processor family and model number.
To check if a guest can be migrated to the target VM Host, use the -s option to the hpvmmigrate
command.
9.2 Known Issues and Information
The following sections describe known issues and information from previous releases that still
apply to V4.2.
9.2.1 Location of Command Used to Initiate Online Migrations of Serviceguard Guest
Packages not in $PATH
The hpvmsg_move command is used to initiate online migrations of Serviceguard guest packages.
This command is located in the /opt/cmcluster/toolkit/hpvm directory, which is not added to the
users PATH variable during installation. To initiate an online migration, use the full pathname
to the hpvmsg_move command. The full pathname to the command is:
/opt/cmcluster/toolkit/hpvm/hpvmsg_move
9.2.2 Possible hpvmmigrate Command Error Messages
You might receive the following message after specifying an hpvmmigrate command:
Can't open VM /var/opt/hpvm/uuids/c0c8a8ee-ac67-11dd-ba00-00306ef3bda7/vm_dev:
(55) VMM not loaded
Opening minor device and creating guest machine container
Creation of VM, minor device 1
hpvmmigrate: ERROR (vmname): Remote message: Target guest exited. Status 2.
hpvmmigrate: ERROR (vmname): Remote message: Unable to start guest on target.
In this case, use the following workaround:
1. Enter the following:
# swremove vmOVMMSW.OnlineMigr-SW
2. Force a reinstall of the 4.1 stack by forcing a reinstall of the T8718AC bundle:
# swinstall -x autoreboot=true -x reinstall=true -s T8718AC
Note, this reinstall reboots the VM Host.
You might receive the following message after specifying the hpvmmigrate command:
Host is not licensed for online migration.
In this case, the workaround is to install the Online VM Migration bundle, T8718AC from the
AR.
