The number of vcpus is set in the configuration file for each vm, see xen_3.0_user_guide/linux_virualization_xen_user_37.html#SECTION03210000000000000000.

I had a problem with my virtualized XP under XEN, I could only assing 2 CPUs to it.

I found out that its a limtation coming from XP and NOT XEN!!!!!

XP supports a MAX of 2 SOCKET PROCESSORS, each one with any amount of cores.

somehow, XEN , sends , or pin, or gives, my CPU, as pures SOCKETS to XP, thats why I could only have 2 processors under XP.

solution .... I have to use any microsft windows SERVER edition, Windows 2003 for example.

good luck people.
