Hi James,

i'll look for the posting you've mentioned.

Here a short overview of the system:

The Hypervisor used is:

(XEN) Xen version 3.2.1-rc1-pre (buildd@buildd) (gcc version 4.2.3
(Ubuntu 4.2.3-2ubuntu7)) Fri Apr 11 01:13:51 UTC 2008

(I know, RC1 pre ... but otherwise _really_ rock solid)

The particular domU is a Windows 2003 SBS 32bit w/ all Servicepacks
installed.

I currently don't know which of the qemu-dm-*.log files were written
with /gplpv enabled. I don't expect any differences but will peek into
this after business hours.


Another domU running a Windows 2003 Server w/ all available Servicepacks
is running without any problems. Config is similar:
name = 'blackberry.hvm'
kernel = '/usr/lib/xen-ioemu-3.2/boot/hvmloader'
builder = 'hvm'
device_model = '/usr/lib/xen-ioemu-3.2/bin/qemu-dm'
memory = 1536
shadow_memory = 8
vif = [
        'mac=00:16:3e:14:82:25,type=ioemu,bridge=eth1'
      ]
disk = [
        'phy:/dev/vg0/blackberry-disk-c,xvda,w'
       ]
boot = 'cd'
localtime='0'
acpi=1
apic=1
pae=1
vcpus=1
usb=1
usbdevice='tablet'
vnc=1
vncunused=1
keymap='de'
vncviewer=0
on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'restart'


You might note that there's a bridge bound to dummy0, this is correct. I
don't
think this causes the problems as the other HVM domU formerly used this
bridge also without a problem.



cheers,

Stephan
