I'm having similiar issues to what Steve had reported in his thread
(http://mail-index.netbsd.org/port-xen/2006/10/08/0004.html) except
even after I include "vif = [ 'bridge=bridge0' ]" in my config file, I
still get the "Error: Device 0 (vif) could not be connected.  Hotplut
scripts not working." error.

brconfig -a shows the bridge0 interface is up and running:
bridge0: flags=41<UP,RUNNING>
            Configuration:
                        priority 32768 hellotime 2 fwddelay 15 maxage 20
                        ipfilter disabled flags 0x0
            Interfaces:
                        ex0 flags=3<LEARNING,DISCOVER>
                                    port 1 priority 128
            Address cache (max cache: 100, timeout: 1200):
                         00:0a:95:d6:1c:8a ex0 4294967143 flags=0<>

Here is my guest domain file contents:
name = "nbsdu"
kernel = "/home/msun/netbsd-INSTALL_XEN3_DOMU"
memory = 96
vif = [ 'bridge=bridge0' ]
disk = [ 'file:/home/msun/nbsd-disk,0x01,w' ]
root = "/dev/wd0a"

I'm running off the binaries from "NetBSD-daily/HEAD/200610250000Z/",
anybody have any ideas what's going on?

Thanks,
Mike
