I'm running bigadv folding within virtualbox on my sr2. It works pretty well
I get about 150k ppd from dual hex cores at 3.5ghz. However, the problem comes because I'm trying to also fold on a gtx 580 using the v7 fahcontrol client. Even though, for some reason, virtualbox is only able to use around 95% of my total CPU time according to Windows, the gpu client is bringing the cpu performance to a crawl. I was getting something like 25k ppd on the gpu at stock speeds while cpu ppd dropped to around 8k (presumably because I would miss the qrb deadline). I've played around with some settings but haven't been able to solve the problem. Has anybody else tackled virtualbox cpu usage problems?

Are you assigning all cores to the Virtualbox VM? If so, what happens if you assign all but one? I'm not a folder, but in BOINC it is always recommended to leave a core/thread open to feed the GPU. Just a thought.
Musky's #1 Rule of Folding - Don't mix bigadv and GPU folding on the same machine. You will do nothing but drive yourself nuts trying to figure out why total ppd sucks. It was like this 3 years ago, and it still holds true today.
If you want to fold on that 580, buy an Atom ITX board with a PCI-e slot (or any other single proc board with a PCI-e slot) and put the GPU there. If you want, I'll give you a board with a working PCI-e slot just to save you the headache that this thread will ultimately cause.
