Hello to everyone.
Here is the problem.
Everything was working ok, the server was rebooted about one week
ago and all virtual machines started without any problem, there
isn't any important update in this week and now I have such problem:
When i try to start new instance i get:
Error: Device 0 (vif) could not be connected. Hotplug scripts not
working.
But the problem isn't in bridging or such stuff. So, if i remove vif
from guest config, there will be same error, but about vdb device.
So, how is possible to me fix this? How can i understand which one
of scrips exactli "not working". I tried to add "touch /tmp/foonar"
to xen-hotplug-common.sh script in /etc/xen, but it looks like it
isn't runned by xm create at all (if i run it by hands - file
appears, but after xm create - don't).
So here is some logs like /var/log/xen/xend.log:

Udev is runnig, tryed to restart it and restart xend. Os is debian
linux (oldstable) with xen 4.0.

in last post.
Os: debian linux oldstable, xen 4.0
Thanks for any advice. Really don't want to reboot the server, and
why actuallly it acting this way? What is 0 in "Waiting for 0"?
First device?
Thank you.
