Bug#534880: linux-image-2.6.26-2-xen-686: domU crashes
Hi,
I recently upgraded my Etch dom0 to a Lenny dom0. Since this time, one
of my virtual machines crashes from time to time. This VM has 8 VCPUS.
The VM is configured with on_crash="destroy" and so I've never seen her
hang because the Hypervisor destroys the machine immediately. After 3
incidents of this type (the Etch dom0 had been running for more than one
year without any issue) in 2 weeks (the VM crashed yesterday and today),
we have restarted the Xend with the dump-core option on and I have
started playing with the generated core (by crashing another VM with a
module triggering a Kernel panic).
I have rebuilt a "linux-image-2.6.26-2-xen package with
CONFIG_DEBUG_INFO." (thanks Valentin for the hint) but I'm not sure the
image has xen built-into it (I apt-get sourced the
linux-image-2.6.26-2-xen-686 package, but I think that building the Xen
kernel out of it requires some special options other than a ):

The multiple VCPUs VM hasn't crashed since this morning, but next time
it happens, I'll gladly provide any information to somebody wishing to
look into the issue.

In the Kamigata area they have a sort of tiered lunchbox they use for
a single day when flower viewing. Upon returning, they throw them away,
trampling them underfoot. The end is important in all things.
