Ok, so I have this new shiny Intel server with a Core 2 Duo Quad  
2.40GHz (or whatever they're called). When I try booting one of my  
XEN2_DOM0 disks (running a 4.0_BETA2 cut in January) on this box I  
get the following:

- -------
**********
We don't support more than two logical CPUs per package!Aieee! CPU0  
is toast...
**********

Reboot in five seconds...
(XEN) Unknown interrupt
- -------

After that there's silence and a hard power cycle is required. Is  
this a known problem?

Also, disabling multi-core in the BIOS (i.e. disabling 3 of the four  
cores) does not help at all. Xen plunges headlong into the wall with  
just as much enthusiasm.

The question is how to get this thing booting with the least amount  
of pain. If the 2 core limitation is a hard limit for XEN2 (i.e.  
"game over") then I won't spend time on that, but if that's something  
that may have improved since January it would be good to know.

Likewise, if this box would run under XEN3 (which I've never tried)  
then that would be interesting too, and a strong reason to try XEN3.  
However, in that case, as I have lot's of stuff that's autogenerated  
for my XEN2 domUs, do I need to make any changes to my domUs other  
than add a XEN3 kernel?

Regards,

Johan
