Subject: [Xen-devel] Creating domain crashes xend with the latest
xenunstable tree
I was able to build and boot Xen using May 16 unstable tree. But the
xend crashes when I create new domain on Fedora Core 3:
See comments below. Will need more info to diagnose this.

The stuff below here shows that xend found domain-1 in the list from xc,
but had no saved info for it. So showing 2 domains in the xm list is correct.
Something bad probably happened during domain create though.
Need to see the config used for the domain and the output from
/var/log/xend.log.
If the problem is reproducible then starting 'xend trace_start'
and posting /var/log/xend.trace would also help.

Another problem I see here is just after I restarted xend, it showed
there were
two domains (Domain-0 and Domain-1) in the list which should be only one
(Domain-0).
