[Xen-users] Error: Device 768 (vbd) could not be connected. Backend device not found.

Hi. I''ve just upgrade my xen 3.0.1 to xen unstable. I noticed that
there is no
vmx driver here, only hvm. Actually I cannot start my VT domain:

root@akira:/etc/xen# xm create bluszcz.hvm
Using config file "bluszcz.hvm".
Error: Device 768 (vbd) could not be connected. Backend device not found.
root@akira:/etc/xen#        


my config:

import os, re
arch = os.uname()[4]
if re.search(''64'', arch):
else:
kernel = "/usr/lib/xen/boot/hvmloader"
builder=''hvm''
memory = 256
name = "bluszcz"
vif = [ ''type=ioemu, bridge=xenbr0, mac=00:00:00:ff:fe:01'' ]
disk = [ ''file:/var/images/img.hd,ioemu:hda,w'' ]
device_model = ''/usr/'' + arch_libdir +
''/xen/bin/qemu-dm''

boot=''c''
sdl=1
