Henri,
To help people understand what you're seeing, can you tell us some more about
your setup? Is it possible that it's a problem like this (which may be
provoked by such setups as virtual disk files stored on NFS, etc...).
It'd be useful to know whether you'd been able to try the upstream XenSource
XenLinux (which really ought to work, if anything does - otherwise it's
definitely an upstream XenLinux bug!). Out of interest, where did you source
the rest of your Xen 3.2 installation - Ubuntu packages, source tarball from
Xensource, or ... ?
Also, I gather this machine is in a remote hosting facility somewhere? Is it
possible that some kind of kernel panic message is being printed to the
display when crashes? Can someone in the datacentre have a look? Better
than that would probably be to get a serial line hooked up so that any
crash-time output can be captured - even if the system is too far gone to log
it to disk. Do you think this might be possible?
Cheers,
Mark
