Guest shutdown problems

[Christian Axelsson]

Hello

I have a problem shutting down xen guests. Using xm shutdown guests get 
shut down but gets stuck in state '---s-d' or sometimes '------'.
When trying to clone a domain when in this state (my original purpose of 
the whole operation) I'll get the error:

   [root@hydra virtinst--devel]# ./virt-clone -o minimal -n new_img -f
     /var/lib/xen/images/new_img.img
   ERROR:  virDomainGetXMLDesc() failed failed Xen syscall
   xenDaemonDomainDumpXMLByID failed to find this domain -490299505

The same errors occurs when for example trying to attach to the console 
using virsh.

I have tried to use 'xm destroy' to kill the guest the hard way but it 
has no effect - the state remains unchanged. I have also tried this on a 
few different guest installations with the same result. A thing worth 
noting is that the output from 'xm list --long' differs, I've attached 
the out put pre boot, after boot and after shutdown. Note how all the 
devices in the guests are missing after shutdown.

Both the hosts and the guests are fedora 8 installations.

Regards,
Christian Axelsson

I have noticed that restarting xend fixes the states. Does that give 
anyone any ideas?

I'm seeing the same thing regardless of shutdown state. I've tried
downloading the latest mercurial virtinst--devel distribution and running
it. 
 
 hg clone http://hg.et.redhat.com/virt/applications/virtinst--devel
cd virtinst--devel

./virt-clone  -o svn -n vpnroute -f /var/lib/xen/images/vpnroute.img
ERROR:  virDomainGetXMLDesc() failed failed Xen syscall
xenDaemonDomainDumpXMLByID failed to find this domain 1732681615

 xm list svn
Name                                        ID   Mem VCPUs      State  
Time(s)
svn                                         24  1024     1     ------    
18.3

Host and guest are both Fedora 8

Anyone know of a fix or workaround? Is this now a known issue? :)

If I can help troubleshoot this in any way please let me know. I really need
this to work.
