Yes you most certainly should be using bigbigadv. I think this is the guide you would have to use to set up a VM, but I'm not positive.I think that's what Lutro0 told me, he's the one who made that site IIRC. I've set up a VM for bigadv but not bigbigadv yet, so we might need to ask lutro0 how it's done because I need to set one up too.
However I do push it pretty hard for others to use as its what I use in all of my bigadv setups.
There is a guide for vmware HERE
If you have any questions please feel free to ask, vmware right now only supports 8 cores and thats on version 3.0 all the newer ones only support 4 (i beleive)
Virtualbox is the only vm that I have used that will allow for easy support of 12 cores, (just set the core count to 12 in the vm and the setup page for the client) You can also do this with a 2600k for an easy core hack. (set the vm to 12 and the setup page to 8)
