Also here is a working example with a different qemu device model.

The config file:

builder = 'hvm'
name = "winxp"
memory = "512"
disk = [ 'file:/media/Vms/winxp.img,hda,w',
'file:/media/Vms/isos/en_windows_xp_professional_n_with_service_pack_3_x86_cd_vl_x14-78118.iso,hdb:cdrom,r'
,  ]
boot = 'dc'
vif = [ 'bridge=virbr0', ]
vcpus='1'

Output:
daniel@dani-ubuntu-xen:/var/xen$ netstat -ntlp
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)
