I'm using xen-4.1.1 and xen-sources-2.6.38 on a Phenom-II-X6 1090T. Paravirtualized domUs work fine but creating a HVM domU causes an instant reboot of dom0. Here is an example config: # cat /etc/xen/bsd.cfg kernel = 'hvmloader' builder = 'hvm' memory = 512 vcpus = 1 name = "bsd" disk = [ 'phy:/dev/raided/beast_root,sda1,w', 'phy:/dev/raided/beast_swap,sda2,w', 'file:/media/Share/Misc/FreeBSD-8.2-RELEASE-amd64-disc1.iso,hdc:cdrom,r', ] boot="d" vnc = 1 sdl = 0 vncconsole=0 vncdisplay=0 keymap="en-us" device_model='qemu-dm' stdvga=0 serial='pty' The bug turned up on the xen-devel mailing list in this thread: http://lists.xensource.com/archives/html/xen-devel/2011-07/msg00922.html Apparently they put it down to a problem with gcc-4.6 but it manifests itself here with gcc-4.4.5 as well. One of the Ubuntu guys backported the fixes that are supposed to be in xen-4.1.2: https://launchpad.net/ubuntu/oneiric/+source/xen/4.1.1-2ubuntu2 The patches apply cleanly here and appears to fix the problem (I've only tested it for half an hour now but the domU definitely starts w/o problems): https://launchpad.net/ubuntu/oneiric/+source/xen/4.1.1-2ubuntu2/+files/xen_4.1.1-2ubuntu2.debian.tar.gz Reproducible: Always Steps to Reproduce: 1. xl create /etc/xen/bsd.conf # (see above for config file) 2. 3. Actual Results: Machine reboots Expected Results: HVM domU running # emerge --info Portage 2.1.10.11 (default/linux/amd64/10.0/desktop, gcc-4.4.5, glibc-2.12.2-r0, 2.6.38-xen x86_64)

please list your use flags for xen-tools && xen
what occurs utilising xm?
Here are my USE flags: app-emulation/xen-4.1.1 -acm -custom-cflags -debug -flask -pae -xsm app-emulation/xen-tools4.1.1-r1 api doc hvm ioemu pygrub screen -custom-cflags -debug -flask The effect was the same when using xm. Now I've been testing the above FreeBSD VM a bit and it seems to run fine if abnormally slow. Raising the number of VCPUs causes kernel panics in FreeBSD but I put that down to FreeBSD's XEN support being crap. Gonna test Windoze for a comparison when I have time.
Matthias; you're very frugal with your xen flags. Would suggest to add xsm or flask to xen-4.1.1., and xen-tools flask too, but don't expect that to solve. Now I've been testing the above FreeBSD VM a bit and it seems to run fine if abnormally slow. So the patch has essentially fixed the crash of hvm. What should dissuade from tying this off resolved?
Fixed in -r5
