FC4, Tyan 2462 SMP, 2 gig, most advanced networking modules built for
Dom0 and DomU.
On first attempt
start xend manually
Create 1st DomU, it crashed, this is consistent even after reboot.

DEBUG (blkif:24) exception looking up device number for sda2: [Errno 2]
No such file or directory: '/dev/sda2'
Created second DomU with this one crashed, no problems.
Created first DomU, xm list now shows two instances
init 0 to second DomU, stop xend , restart xend , first DomU get created
with no problems.

xend.domain.unpause ['inyoureyes-domain3', 6]
inyoureyes-domain2 started fine
inyoureyes-domain3 got stuck at
xen_net: Initialising virtual ethernet driver.
xen_net: Using grant tables.
For these tests I have most of the advanced networking modules being
built if that matters.
The good part is that xm destroy is able to kill inyoureyes-domain3.
>From what I have been seeing xm destroy problem is contained to crashed
and duped Domu's only, this appears to be consistent to what I read on
the list.
I restart inyoureyes-domain3 and xm list shows it as paused, issuing an
xm unpause it now shows blocked, but issuing xm console fails with
xenconsole: Could not read tty from store: No such file or directory.
Than I issue xm list and inyoureyes-domain3 is no longer showing up.

Another Caveat
It appears that
ERROR (process:37) [network-bridge] Cannot find device "xen-br0:1"
Stops happening after a few restarts of xend.
But this message is consistent for any domains.
(blkif:24) exception looking up device number for sda2: [Errno 2] No
such file or directory: '/dev/sda2'
Seems not to matter as the DomU gets created though.
Also seeing some issue with memory, once the first DomU crashes I am
unable to recover the memory assigned to it. Stopping xend and purging
files in /var/lib/xenstored/store/domain/ no affect. Appears to
cooincide with this trace.
