[Xen-users] Error:Device 76 (vbd) could not be connected.

[CS - Ronald Wiplinger <ronald@xxxxxxxxxxxxxx>]

I combined several scripts and hints to install Ubuntu server on an 
Intel Pentium D (with VT) and use LVM.

When I reboot the new Xen system I find these last  lines in 
/var/log/messages:
Jul  4 17:03:52 CS-Ron0 kernel: lo: Disabled Privacy Extensions

When I start ubuntu, I see this (I start via ssh):

xm create -f ubuntu
Using config file "/etc/xen/ubuntu".
Error: Device 769 (vbd) could not be connected. Hotplug scripts not working.


/var/log/messages got from this try following additional lines:

Jul  4 17:06:23 CS-Ron0 kernel: device vif1.0 entered promiscuous mode

Jul  4 17:06:33 CS-Ron0 kernel: xenbr0: port 3(vif1.0) entering disabled 
state

The script I use is:
grep -v ^# /etc/xen/ubuntu |grep -v ^$
kernel = "/boot/vmlinuz-2.6.16-xen"
memory = 1024
name = "Ubuntu"
vif = [ '' ]
disk = [ 'phy:XenDomains/ubuntu,hda1,w' ]
root = "/dev/hda1 ro"
extra = "4"


What do I miss?

bye

Ronald
