[Xen-devel] 2.6.38-rc5-11-xen kernel oops when destroy DomU
Hello this is what happens I create a xen domU using ether of two methods xm
create or virt-manager, then destroy using ether of two methods (or shutdown in
the case of virt-manager.
I revive a kernel oops upon destroying the DomU.
SYSTEM
openSUSE_Factory/openSUSE-11.4
Arch: x86_64
STEPS TO REPRODUCE
1.)Install:: kernel-2.6.38-rc5-11-xen
virt-manager-0.8.5-53.1.x86_64
libvirt-0.8.8-107.1.x86_64
xen-4.0.2_02-99.1.x86_64
note also install all required libraries for these packages mentioned.
2.)Create a DomU VM:: using virt-manager, start the program as (root) if in a
xsession under another user simply use the gnome desktop menu >> Computer
>> More Applications >> search for Create Virtual Machines or
Virtual Machine Manager (if you already created a domain) Go through the process
of specifying the phy drives and the settings they do not really matter for this
BUG.
3.)Destroy/Shutdown a DomU VM:: using virt-manager right click the domU VM and
select shutdown.
WHAT HAPPENS
The kernel oops should appear on the current TTY and lock out Xorg completely..
I havent done a lot of debugging as I dont know where to start, I suppose I
could try using the sysrq keys , I am not entirely sure that a kernel panic
occurs afterward, I do not think it does, however the oops does seem to lock out
my GFX card hardware is a Gforce 250GT 1G mem
motherboard is a Nvidia board Nforce 680i
