[Xen-users] HVM failing. Tips please?

[Aleix Dorca <adorca@xxxxxx>]

Hi people,

I have several Xen Dom0's working. Those that have PV domU's work  
awesomely and without any problems. The ones that have HVM domU's fail  
once every two weeks (more or less). Here's the setup:
Dell PowerEdge 1950 III
Ubuntu 8.04.1 (64bits) with Xen 3.3.0 compiled over the linux-image- 
xen from Ubuntu.
HVM domU's are Windows 2003 Server Enterprise
I've set the clocksource to "jiffies" to avoid high load fails (this  
reduced the failing A LOT).
All disks are accessed via iscsi.

As said every now and then Dom0 hangs completely. No net access  
whatsoever... all gone. I have to manually stop the machine and  
restart it.
My domU config file is super simple... here's an example:

### Config ###
kernel = "/usr/lib/xen/boot/hvmloader"
builder='hvm'
memory=1024
name='domu'
shadow_memory=8
vcpus=8
vif = [ '' ]
disk = 	[ 'phy:/dev/disk/by-path/ip-xxx.xxx.xxx.xxx:3260-iscsi-iqn. 
2008-08.xx.xx:domu-lun-0,hda,w' ]
on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'restart'
device_model = '/usr/lib/xen/bin/qemu-dm'
sdl=0
vnc=1
vncviewer=0
stdvga=0
serial='pty'
usbdevice='tablet'
### Config ###

I'm asking you people for help desperately. I've been dealing with  
this for months now. Any help will be highly appreciated. Please,  
please, please!! :)
Thanks a lot,

Aleix.
