Thread-topic: Xen 3.0.0 released!
Just gave 3.0 a spin.  Had been running 2.0.7 for the past 3 months or so 
without problems (aside from intermittent failure during live migration).  
Anyway, 3.0 seems to have an issue with my machine.  It starts up the 4 domains 
that I've got defined (was running 6 user domains with 2.0.7, but two of those 
were running 2.4 kernels which I can't seem to build with Xen 3.0 yet, and I 
see from the readme file it isn't yet supported so I'm not complaining :-)  
Once the 4 user domains starts the machine will suddenly reboot.  I added a 
sleep inbetween individual domain startups in xendomains and was able to get it 
to start up without rebooting, but then after about 5 or so minutes the machine 
rebooted again.

I turned hyperthreading off on the machine and it seems to be able to boot with 
all 4 user domains just fine without the need for sleeps inbetween (very 
consistently dies if HT is enabled and I don't sleep a little while between 
domain starts).  So I'm leaving HT off for now to see if it remains stable with 
HT disabled.

I was going to report this on bugzilla, but bugzilla.xensource.com is giving me 
a server error right now.
