I've been working on getting a xen dom0 running on arch linux. I've got to the point where I can start xen domu's and everything on them works.
The issue I'm having is if I stop one in any way, I cannot restart a domu or start a new one. It fails with the error message "Error: Device 0 (vif) could not be connected. Hotplug scripts not working." After it fails the only way I've found to get it going again is to restart the dom0.

I have the same problem. Could someone help us?

I "fixed" it. Apparently the newer udev versions (>151) don't work properly with xen.
Solution: Downgrade to udev-151.
In my case, I downloaded http://schlunix.org/archlinux/core/os/x … pkg.tar.gz and ran: pacman -U /path/to/udev-151-3-x86_64.pkg.tar.gz
I then restarted and my errors went away.
Hopefully this helps someone!
