Dead domains don't disappear from xm list

Dead domains don't disappear from xm list

[Stephen Childs]

Hi,

When a domain shuts down it seems to stay visible in the output of xm list 
(see below) even if I do an 'xm destroy'. Has something changed (they used 
to disappear just fine for me)? I am running Xen 2.0 (fairly up-to-date).


Name              Id  Mem(MB)  CPU  State  Time(s)  Console
Domain-0           0      395    0  r----   2377.2

As you say, dead domains usually go away just fine.
If a domain doesn't disappear from the list, the usual
reason is that according to xen itself it still exists,
even though xend has tried to destroy it.
It's also possible there's a bug in xend.

Is there anything in /etc/log/xend.log?

(Only do this if your domains aren't important)
Do the zombie domains go away if you restart xend?
