[Xen-users] Cannot run Stub domain in Ubuntu

[fronter <gavin09@xxxxxxxxx>]

Hi all 

Thanks for reading this article...

I install Xen 4.1.2 with Ubuntu 10.04 64-bit server. 

I can run Para-virtualization and  HVM with qemu-dm. 

I want to try stub domain, but it fails. 

Here's my log and cfg below. 

cat stub-xl

kernel = "/usr/lib/xen/boot/hvmloader"
builder='hvm'
memory = 2048
name = "rtes-big-stub-1"
vcpus=2
vif = [ 'type=ioemu, bridge=xenbr0' ]
disk = [ 'file:/home/rtes-big/guestfull1/ubuntu.img,hda,w' ]
device_model_stubdomain_override = 1
boot="c"
sdl=0
vnc=1
vnclisten="0.0.0.0"
vncconsole=1
vncpasswd='rtes'
stdvga=0
serial='pty'


sudo xl create -c stub-xl

I know xen-hotplug.log tells me I missed something. But I can't figure it
out.....
Thanks for reading this page....
