For details on VM maintenance mode, refer to "D.3 Functional Differences between Products" in the "Design Guide VE".
VM maintenance mode can also be set or released from the command-line, using the rcxadm server set command.

15.3 VM Home Position
This section explains VM Home Position.
By configuring the VM Home Position in advance, it is possible to restore VM guests to their original VM host using only one operation
when they have been migrated to a different VM host for operation or maintenance needs.
This enables restoration of multiple VM guests to their original locations without the need to record their original locations.
15.3.1 Setting VM Home Position
When configuring a VM Home Position, the relationships of operating VM guests and registered VM hosts are retained.
Setting is only available when more than one VM guest exists.
Information
- When registering a new VM host, as the relationship between the VM host and operating VM guests is not yet retained, reconfiguration
of VM Home Position is necessary.
- When a new VM guest is detected, reconfigure the VM Home Position so the relationship between that VM guest and its VM host is
set.
- When configuring the home position of a system, all VM Home Positions of VM guests are set to the current configuration.
- When configuring home positions for each VM host, VM guests will be associated with the VM host on which they are operating.
The relationships are retained, even when a VM guest associated with the VM host is operating on another VM host.
