Package: xen-utils-4.0
Version: 4.0.1-1
Severity: important
I'm running a 32-bit Ubuntu 10.04 domU on a 32-bit Debian squeeze dom0.
xm create works fine, but whenever I try to reboot this domU it fails with
the following traceback in xend.log:

I'm under the impression that the problem is that on reboot, domid is still
set while the .image component of the XenDomainInfo object has been reset.
On create, on the other hand, domid isn't set until a later stage so the
condition at line 107 of balloon.py evaluates to false and the getBitSize()
method call is not attempted. I don't consider myself sufficiently familiar
with the code to suggest a solution.
