[Xen-users] Xen 3.0 Zombies?

[Martin Schipany <elcondor@xxxxxxxxx>]

Hi!

When I tried to start a domU where the root-device (/dev/md/5) was still
mounted in the dom0, I got an error about the dev being mounted. A "xm
destroy domain" resulted in a Zombie and a Kernel-Ooops (following below).
When I tried to start the domain after unmounting the device, it shows up
in "xm list", but doesn't start (but can be destroyed)

Is there anything I can do about the zombies exept for KILLING the xend
process? shutting down doesn't work, since it tries to shutdown/destroy the
zombies ...
