Hi
I've installed xen hypervisor 3.0.3 on CentOS 5.5 from CentOS repository.
The hardware I use is a Tyan server with 48 cores( 4*12-cores processors ).
The original CentOS kernel 2.6.18.194 can recognize 48 cores perfectly, but when I switch to another kernel to use xen, the kernel recognize only 32 cores!
I tried to recompile the kernel by changing the maximum number of cpu in .config file, but nothing changed!
Can anyone help me?
Regards
