I've recently upgraded pkgs an Opensuse 12.3 + XEN 4.3
(xen-4.3.0_08-264.1.x86_64) server.
It's got two guests set for auto-launch @ boot.
It's been working fine for awhile. The guest cfg's have not changed in
ages. Just the upgrade has occured recently.
Now, reproducibly after boot, one Guest is missing,
xl list

here? systemd?

but launches manually
xl create /etc/xen/auto/test1.cfg
xl list

test2 2 1024
4 -b---- 13.8

2 -b---- 2.3
and functions normally.
checking xen boot logs, I find these, new failures

Those
"event_channel.c:233:d0 EVTCHNOP failure: domain 2, error -22"
errors are new to me.
Looks like a XEN issue. I've seen recent work on event channel deadlock
on the dev list, but my xen's logs don't mention anything evtchn-related
since ~ Nov 2011.
Before deciding to file a bug, I need to do some local troubleshooting.
Any suggestions as to what this might be about, or specific additional
info that might be enlightening?
