[Xen-users] Error: Device 0 (vif) could not be connected. Hotplug scripts not working. - KERNEL BUG

["Juan Antonio Vera (Internet)" <javera@xxxxxxxxxxxxxx>]

Hi all.

I've a xen dual core server with suse 10.1 and xen 3.0.2 (from rpm suse 
package). I was working with them without any problem for
6 months but now I've a problem. On this intallation are configured 6 
domains (1 database server, 1 intranet server, 2 firewalls, 1 web server and
domain 0) and I need to create one more called gis but the system gives 
me the next output when I try it:
# xm create -c gis
Using config file "gis".

This  the  domU gis configuration file:
========================

kernel = "/boot/vmlinuz-xenpae"
ramdisk = "/boot/initrd-javera-reiserfs.gz"
memory = 64
root = "/dev/hda1"
name = "gis"
disk = ['file:/var/tmp/xen/fw1.vmdisk,hdd1,w']
vif      = ['ip=1.2.3.4, mac=aa:cc:00:11:11:22, bridge=xenbr-I' ]


Normally, when I need create one domain more I copy a working 
configuration file to a new, modify tne mac address, disk image and the name
and leave untouch then kernel and ramdisk entries, so the problem has to 
be from my xen environment and not from my configuration file.
In addition, on the /var/log/messages appears the following message:
