[Xen-devel] Problem starting xend in latest 3.4 release candidate

[Tim Post <echo@xxxxxxxxxxxx>]

Hi,

Several days ago, I upgraded to the latest 3.4 release candidate.
Everything went very well, no problems whatsoever. I re-booted without
issue.

Several days later (today), I can not get Xend to start. There have been
no changes in Python, no configuration changes, no OS updates ..
nothing.

This is the output in xend.log is below. Can someone please shed some
light on what the cause might be?

I'm using Debian's 2.6.26 kernel on x86_32, Python 2.5.4. Xenstored is
started, I can do a xenstore-ls and see dom-0's event channel, but
nothing else since Xend has not set it up.

I'm really, really bewildered. Any help is appreciated. I can't tell if
this is due to upgrading, or if some other strange problem has appeared
on my system. My Python is not the best :)

Last night, it worked. Today, it doesn't .. and I can't think of
anything that happened overnight , especially since the system was shut
down.

Thanks in advance.
