[Xen-users] VMX guests crash on HP DL320 G4 servers.

[Mark Ruijter <xendev@xxxxxxxxxxx>]

We have been testing recent versions of Xen on Fedora Core FC5 with various kernels.

During the first test we had the standard FC5 kernel / xen packages installed:
xen-3.0.1-4.x86_64.rpm / kernel-xen0-2.6.15-1.2054_FC5.x86_64.rpm
This setup crashes with modified guests doing live migration and also crash with unmodified guests.

The version that we're currently using is:
 xen-3.0.2-4.x86_64.rpm with kernel-xen0-2.6.16-1.2202_FC6.x86_64.rpm
I have also tried building xen from the unstable tree with the same result.

The hardware used is a HP DL320 G4 and modified guests are running fine on it.
Below is de qemu logging of an attempt to start Windows XP.

Booting from CD-Rom...

It makes no difference if the guest OS is redhat or Windows XP.
Windows XP will boot until it has loaded mud.sys, redhat crashes on running anaconda.
When booting XP from the installation media it will run until it displays "Starting Windows".
After that it will freeze.

Listed below is the configuration file that I use:
kernel = "/usr/lib/xen/boot/hvmloader"
builder='hvm'
memory = 512
name = "winxp"
vcpus=1
pae=0
acpi=0
apic=0
vif = [ 'type=ioemu,bridge=xenbr0,mac=00:15:3e:63:73:f2' ]
disk = [ 'phy:/dev/sdb,ioemu:hda,w' ]
device_model = '/usr/lib64/xen/bin/qemu-dm'
cdrom='/images/en_winxp_pro_with_sp2.iso'
boot='d'
sdl=0
vnc=1
vncviewer=0
stdvga=0
ne2000=0

Is there a patch or fix around somewhere that I can try?

Thanks in advance,

Mark Ruijter.
