    xen doesn't boot --12.10 install

    I have a fairly new intel motherboard (hopes of getting SR-IOV working on xen).

    When I install and try to boot xen over 12.10 ubuntu, I see the expected xen text scroll and then ... stall at black screen.
    After a LONG time after one boot, I see:
    [ 367.571827] BUG: soft lockup - CPU#9 stuck for 23s! [swapper/0:1]
    (yeah, I know that should be about 6 minutes)
    trying to switch to simple virtual terminal screens doesn't work at all.

    Everything works like a champ with a "normal" boot (vs. xen). ?
    That's not working out for me at all.

    I have to use the big button to cycle the system. Are there xen logs I can see and share when booting into linux? ... or something?

    when I boot the same xen disk on another (older and less powerful) system, I am able to boot xen ... mostly. the graphical screen comes up with a mouse pointer (responsive to movement) on a black background. There is a blinking underline cursor at the top left corner. I am able to go to virtual terminals and login. this confirms the lines I'm hoping for per:
    when I type
    sudo xm list

    It still is a big problem for me that I don't have graphical environment working and even a bigger problem that the newer system doesn't boot xen.
    Is there some ubuntu xen mailing list I can reference / work with?
    I can contribute debugging effort and help xen to work with newer systems.
    Is there some place I can get source code for the package used by
    apt-get install xen-hypervisor-amd64
    Is there some process to go through for filing a bug? ubuntu xen does not work on hardware that ubuntu itself supports.
    Some good tips or references would be much appreciated.

    I can confirm the problem here, too. No working solution yet! XEN loads and after extracting the boot-image it results most often in a automatic reboot.

    Do you have some solution here?

    See the red warning in the first post about 4.1.3-3ubuntu1.5. Use the "force version" option in Synaptic (or apt-get) to downgrade to an older release of the following packages:
    libvirt-bin libvirt0 libxen-4.1 libxenstore3.0 python-libvirt xen-docs-4.1 xen-hypervisor-4.1-amd64 xen-system-amd64 xen-utils-4.1 xen-utils-common xenstore-utils
    Let me know if it works.
