Re: [Xen-users] Frequent para (Linux) domU hangs

When a VM hangs, xentop actually thinks its running (its state = r and

Sounds like a common problem with xenconsoled

This is the advice I had from Ferenc Wagner on 18 Jul 2009

It isn't that simple.  Other guests lock up when they fill their
console buffers, apparently.  But new guests seem to work fine for
me.  Just try it, when you next experience this: stop xend, kill
xenconsoled, start xends.  Don't touch xenstored!  If everything
returns to normal, then this was it.  If not, then something else. :)

It's worked for me every time.
