hi,

I am trying to use xm to create a new domain (normally I am using my own
home-brewed tools, but I would like to play with xm migrate to benchmark
it against my self-migration impl.), but when my domain has a vif
configured I am running into the following timeout error:

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

The config-file for the domain looks like this:

name="cons"
memory=64
kernel="/root/vmlinux"
ramdisk="/root/domUinitrd"
vif=[ 'mac=aa:00:00:00:00:02, bridge=xen-br0' ]
root="/dev/ram ro init=/linuxrc"

Xend has been started and I am using the standard xen-3.0.3 vif scripts
and config files.

For hotplug, my system is running udev. The
file /proc/sys/kernel/hotplug is empty, not sure what that means.
ifconfig shows no vif for the domain. The strange thing is that it all
works fine using my 'buscreate' tool for creating a similar domain.

Does anyone have a fix for this?

Thanks,
Jacob
