Dom-U deleted after introduction of the parameter "change_home_server" in the VM configuration

This document (7006885) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 11 Service Pack 1

Situation

"xm list" does not more list the Virtual Machine (VM) after a change of the VM by
introducing the parameter "change_home_server False". This change might have been introduced
manually or automatically during an "xm migrate" operation.

The "/var/log/xen/xend.log" does then show the following similar messages after execution of
"xm shutdown <VM>":
