In my previous post, I was asking questions about how to get guest VMs
to cleanly shutdown and start back up when the host shuts down and
starts back up.
Newbie Virt Questions and comments on wiki/Docs/Fedora8VirtQuickStart
I have made some progress on this issue by complete accident.
Previously I had a Fedora7 guest stored in an LVM partition.
I just tried a Fedora8-RC3 guest stored in a regular file.
Now the behavior is that if the guest is running when the host is shut
down, it appears to try to start it back up after the host boots back
up. BUT, the guest restore fails with the following:
I would greatly appreciate any tips on how to stabilize this environment
to get clean guest shutdowns and start ups when the host shuts down and
starts up. Thanks in advance.
