You need 64-bit CPU with virtualization support in it (doesn't matter if AMD or Intel - it's compatible).

To check, if virtualization support is in CPU (checked flag "vmx" or "svm" has to be in output), run as root:
for AMD CPU:
egrep vmx /proc/cpuinfo

for Intel CPU:
egrep svm /proc/cpuinfo

In positive case the output looks like:
[root@redhat proc]# egrep vmx /proc/cpuinfo

Dear OpenNebula Team,

I want to download OpenNebula and see there are options like OpenNebula 3.2.1 Ubuntu 10.0.4 amd64 and OpenNebula 3.2.1 CentOS 6.0 x86_64.

For OpenNebula 3.2.1 Ubuntu 10.0.4 amd64, we have to buy AMD processor, but for OpenNebula 3.2.1 CentOS 6.0 x86_64, what type of processor should we buy?

Thanks,
Q.S.
