[Xen-devel] vif interface creation problem with xen unstable

[Adam Heath <doogie@xxxxxxxxxxxxx>]

I'm using vif-route as my network script.
I've added set -x to the xen hotplug script change.  I've also added a
command to do a listing of the xenstore directory.  Here's the snippet:

==
++ ip=
+++ xenstore_read_default backend/vif/4/0/ip ''
+++ xenstore-read backend/vif/4/0/ip
xenstore-read: couldn't read path backend/vif/4/0/ip
+++ echo ''
++ ip=
++ xenstore-list backend/vif/4/0
mac
state
handle
script
frontend-id
domain
frontend
++ XENBUS_PATH=backend/vif/4/0
++ vif=vif4.0
==

There is no ip value set.  However, ip *is* set in the config file.

If I strace xm create, I get this:

The vif device looks wrong.

Here's the changeset I am using:
