Code:
sasha@reactor: cat /proc/cpuinfo

The above file in proc should contain the info you want?

sorry for the incomplete question:
I am running ESX 4 on Intel x64 hardware. So I can see that /proc/vmware/cpuinfo reflects the 8 cores while entry under /proc/cpuinfo shows the following:
Code:
[root@vmqa038-km-hp360 ~]# cat /proc/cpuinfo
