Same for me on opensuse 11.2. Had to rollback to opensuse 11.1 (kernel 2.6.27.37). I guess it is when IO load is generated from domU and the domU lives in a "raw device" such as a prtition or a lvm volume. I could not crash the machine, if domU lives in a file. An alternative is to add "mem=4G" as parameter for the xen hypervisor in grub: kernel /xen.gz mem=4G See Bug: https://bugzilla.novell.com/show_bug.cgi?id=551695 Svoop wrote: > Hi > > I'm running a i7-920 with 4G RAM and two SATA HDs in a softraid.
