Comment 3 Steven Rostedt 2007-08-20 14:15:51 EDT
How exactly was the guests started. Did you run a simple "xm create" in two
different windows?  I'm currently running two XP Guests as well as a 2003 Guest.
How much memory did each guest have (the config states 256). I'm running each of
mine with 512 (will start again with 256).

So far, I haven't had a crash.
Comment 4 Steven Rostedt 2007-08-20 15:08:28 EDT
Could you also post the config for "both" the guests that were running.
Comment 5 Zhao Yunfeng 2007-08-21 08:40:37 EDT
The config of the two windows are basically the same.
I just changed the domain name and disk images.

I create the two windows guests, with the command:
"xm cr config1;xm cr config2"
Comment 6 Steven Rostedt 2007-09-07 09:51:49 EDT
Bugzilla 249409 had the same symptom and a patch to fix it went into release -44.

Could you retest with the latest and see if the problem goes away?
Comment 8 Zhao Yunfeng 2007-09-14 02:58:53 EDT
I have retested it on snap 6.
The issue has already been fixed.
Comment 9 Stephen Tweedie 2007-09-14 09:00:41 EDT
Thanks, will close this as a dup of that other bug, then.
