Thanks for the suggestion; I'll try that next time a VM hangs. I've read
some reports that restarting xend with running VMs might not be safe
(others say it is?).
It won't fix my problem though: getting hanging production VMs going
again still requires interaction (restart of xenconsoled versus restart
of VM). Are there fixes available for xenconsoled?
Having said that I did notice console buffers filling up a while ago and
fixed that problem by making sure that log messages do not end up on the
(xen) console. When I connect to the console, I can see that indeed no
log messages have been sent there; it just sits at the login: prompt and
plays dead.
regards,
Jan
