At the bottom of this email is the latest error log snippet.

Are lines like the following normal?
INFO (XMLRPCServer:156) Opening Unix domain socket XML-RPC server on
/var/run/xend/xen-api.sock; authentication has been disabled for this
server.

This lines below shows Xend is actually crashing and restarting when
the guest is trying to be started
[2008-12-13 12:44:58 5833] CRITICAL (SrvDaemon:231) Xend died due to
signal 11!  Restarting it.
[2008-12-13 12:44:58 6001] INFO (SrvDaemon:331) Xend Daemon started

It thens does a recreate, which adds a domain in a paused state.

xm create on the command dies out.

xm list shows an unnamed domain.

(my config was sent in the last email for reference)

Below is the full output of the xend.log

Once I am able to test again I will check the corresponding xend-debug
and domain-builder log
files.

Let me know if you have any thoughts on what to try next.
