Hi there!
After a reboot, the virtual XP hosted on a Debian squeeze did not come
up automatically, with the following error:

=====
First, the CHECKSUM problem is an old one (see #598330): while this is
simply a warning, IMHO it should be fixed in the backports as well.
Second, after some debugging I discovered that I forgot to close a case
statement for the GUEST_NAME in the hook script I provided in:
<http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=637219#52>
However, the fact that there is no mention of the meaning of 'error code
512' in the official libvirt wiki means that it is almost impossible to
understand if the error is in the hook script or in libvirt-bin. FTR, I
was expecting 'error code 256' instead:
<http://www.libvirt.org/hooks.html#return_codes>
Thx, bye,
