[Xen-users] Debian can not start domU

[Lars Wilke <lw@xxxxxxxxx>]

Hi,

i guess this is a frequent error:

   Error: Device 0 (vif) could not be connected. Hotplug scripts not working.

i have created a symlink in /etc/udev/rules.d to the xen-backend.rules

If i try to create a vm without a network config, a similiar error message
comes up:

   Error: Device 769 (vbd) could not be connected. Hotplug scripts not working.


I am really stuck now. I have searched quite a while to find a solution but all
tries where unsuccessful. Therefor i am asking here, maybe someone has some 
ideas
what i could try. I am running debian packages from unstable.

I am adding some output of various commands for your reference and a xend.log 
and
a strace log.

Any help is really appreciated, thanks

regards
