Xen users - Jul 2007 - How to deal with shutdown event for HVM DomUs?

Hello,

 

            I have following task - having Xen server with some DomUs with
Windows as guests. Because it runs as HVM only and cannot use the
paravirtual mode, it has also problems with receive of the "shutdown"
event
of the whole machine - so it means, if the Dom0 is shut down, the DomU
domains are destroyed without beeing correctly shut down and the windows
services etc. cannot be shut down correctly, what is not very good for the
data integrity and stability of the HVM (Windows) guest.

 

            What is the best approach to solve this problem? The only way I
can imagine at this moment is to make the save of the DomU domain if the
Dom0 shutdown occurs and then also by the Dom0 start perform the restore of
the DomU domain. 

 

            Can this task (automatic save and restore of the running
domains) be done with the help of some existing tool, or do I have to write
the scripts myself, which will make it by the shutdown/start of Dom0? I
think, this could be the task for Xend, but at this moment I did not found
in the documentation (http://wiki.xensource.com/xenwiki/Xend/Stateless)
nothing in this way...

 

            Or is there any other way how to solve this problem with the
uncleanly shutdown HVM DomUs?

 

            Any advice or pointer to some documentation would be
appreciated...

 

            With regards, Artur.
