Hrm. The device simply isn't on the bridge. Does "ifconfig -a" in dom0
show a vifX.Y device for the domain? You previous xenstore log suggests
it should be there but lets double check.

Do you get anything in the logs under /var/log/xen?

Are your hotplug scripts running at all? One trick I usually use is to
add to the top of vif-bridge something like:
        exec 1>>/tmp/hotplog.log
        exec 2>&1
        echo "`date`: Running $0 $*"
Then any hotplug script which gets run will dump its output
to /tmp/hotplug.log.

http://wiki.xen.org/wiki/Reporting_Bugs_against_Xen lists a bunch of
configuration files and logs which might be of interest, at least to
skim looking for anything odd.

Ian.
