[Xen-users] restarting xend error when creating DomU

[Peter.Weiss@xxxxxxxxx]

Hello

on my opensuse 10.0 I've a problem since upgrading to xen-3.0_8259 rpms:

Each time a issue a /etc/init.d/xend stop/start I get an error when creating
a Domain:

# xm create -c xen1
Using config file "/etc/xen/xen1".
Error: Device 0 (vif) could not be connected. Hotplug scripts not working.

After rebooting Dom0 everything works.

>From the log I see:
