Hi,

>From time to time this problem pops up. The server runs happily. VMs are
started and restarted a number of times. Then after a while a VM (as far
as I know always a HVM) no longer boots. A reboot of the server "fixes"
the problem but I'm looking for a better way.

I've noticed that subsequent attempts to start this particular (HVM)
domain will start building up entries in xenstore. I've already tried to
remove them with xenstore-rm, which doesn't make a difference.

It seems that in this case "vif4.0" is getting stuck. When the VM is
attempting to boot, xentop shows a (very brief) error message at the top
saying that vif4.0 exist but the domain doesn't. vif4.0 doesn't show in
ifconfig but it is listed in /sys/class/net.

My gut feeling tells me that if I would be able to get rid of vif4.0,
I'd be able to start the VM again.

Any ideas how I can get this unstuck so I can start this VM without
rebooting dom0 and all other domUs?

regards,
Jan
