   Yes, that is the case.  16225 works fine.  On 16226, the domu hangs,
then gives me a vkbd error:

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

Here's was I see in the qmeu log file:

xs_read(): vncpasswd get
error. /vm/c766b61d-58e1-8efe-b853-40addbd451ae/vncpasswd.

FB: Waiting for KBD backend creation
Doing backend watch on 
Watch for dev failed

The same failure happens in the qmeu log with tip.  It seems odd to me
that xenfb_new() can return failure, but we don't make use of the return
value from xenfb_wait_for_backend().  I also attached the xenstore-ls
output.  This was domid 5 for this latest attempt on cset 16226.
Thanks,

	Alex
