Description Wesly Chen 2007-06-21 02:23:16 UTC 
Description of problem:
When domain-0 is rebooted without shutting down the domU gracefully, it creates 
an incomplete save file in /var/lib/xen/save/<domU name>, and you can not start 
that domU anymore unless you remove /var/lib/xen/save/<domU name>

Version-Release number of selected component (if applicable):
xen-3.0.3-25.0.3.el5.x86_64

How reproducible:

Steps to Reproduce:
1. create a runable domU, say rhel3_32

Please trace back the time stamp before 17:30 June 20 in the log. Because I have
remove the /var/lib/xen/save/rhel3_32 before reboot after 17:30 June 20.

Comment 6 Daniel Berrangé 2007-06-21 12:43:21 UTC 
The xend.log file shows that  rhel3_32  is a fully virtualized guest. Save and
restore does not work for fullvirtualized guests in Xen 3.0.3.

Comment 7 Wesly Chen 2007-06-21 16:29:33 UTC 
OK.
If fully virtualized guest is not supported in in Xen 3.0.3, then it should not
save the fully-virtualized domU when the dom0 reboot.
It should destroy the fully-virtualized domU to avoid restoring issue, shouldn't it?
Otherwise, when dom0 crashes or power outage, all the fully-virtualized domUs
will have the issue to bring on up.
