I'm running current compiled with CLANG on the latest stable virtualbox 
under Win7. It works good, the only issue I had a couple of days ago when 
compiling world with -j4 (I've a 2-core with HTT) was that the CPUs were 
not raising their speed. They were just running on 780MHz and the 
compilation took half a day. A reboot of windows 'fixed' this. Normally if 
I do such a compile then both CPUs go up stable to 3.3GHz. I suspect that 
this is a bug in the BIOS or Windows where the frequency control gets 
stuck.

Maybe first try to check with hwinfo what your CPUs are doing.
