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 ): crash /boot/System.map-2.6.26-2-xen-686 vmlinux 2009-1029-1350.15-kek.24.core crash 4.0-6.3 Copyright (C) 2002, 2003, 2004, 2005, 2006, 2007, 2008 Red Hat, Inc.
