Virtualbox an Esxi5.0 Abstraction layer

So last night I installed Esxi5.0 "freeware" in virtualbox. Its pretty straight forward, and I mean just install from iso but there are a few "non-issues". Esxi5.0 has to be installed on something that is at minimum a dual core, and you have to devote both CPU's to virtualbox. If installed on an AMD Phenom its crying about not having the virtualization bit enabled on my cpu. Boo hoo. ;)
