Hello,
I have a problem with domU starting. I use
vif=['']
configuration option for setting network.
When the domain starts it hangs for a while and then
ends with an error:
[root@fik ~]# xm create -c vmid=1
Using config file "/etc/xen/xmdefconfig".
Error: Device 0 (vif) could not be connected. Hotplug scripts not working.
I have googled some pieces of advice but nothing applies for me
(I have enough loop devices, I cannot install hotplug package since it is
no longer used in FC5).
Does anybody have a hint what can be wrong?
Some (hopefully) useful logs:
