Hi
 We have a client that shows and updates the current
dom status periodically. When I issue a kill to a dom,
the next call to xend.domains(1) fails with the
VMError.
It seems that Xen is still in the process of killing
and the xend.domains call is trying to get information
and seeing some partial stuff, leading to this
problem.
This particularly happens when vif is set with mac
address and bridge specification.
See attached stack trace and xm info to get idea about
the environment.
Is this a known problem ? Any patches available ?
Any workaround that can be coded in the client ? 
(I have tried some lame waits.. but there is another
thread that runs into this.)
Thanks
/Jd
