[Xen-users] xenstore-read: couldn't read path /local/domain/1/vm

I'm trying to boot an HVM guest but it immediately shutsdown with few errors. I originally thought it had something to do with file backed 
vbd's but I used tap:aio and even used losetup manually to attach to
/dev/loop* and used phy: backed vbds.  All produced near-identical
results.  From what I can tell there are not really any errors being
reported other than in xen-hotplug.log. If anyone can see something wrong please let me know. 

Output from xen-hotplug.log
Nothing to flush.
