Jsmooth1992,
I've never used Oracle VM, but my very general understanding suggests that a high memory bandwidth, reasonably high clock speed, high double precision capabilities, a high core count to simulate multi-threaded applications, fast RAM, and a substantial high performance and massive storage RAID configuration are desirable features. This suggests to me an LGA2011 for the memory bandwidth, using dual Xeon's possibly dual 6 or 8 core, ECC error correcting RAM - perhaps 64GB, for precision, and since Xeons do not have integrated graphics, a moderate workstation graphics card- Quadro or Firepro is necessary. Overclocking is not recommended because of stability issues on long slogs.
Of course, the ultimate machine for this use could have a substantial cost- $7,000-$10,000 (dual 8 core E5 Xeons), but a quite capably system might still be $4,000 or more.(single 6-core Xeon, 32GB RAM). If the budge t is quite restrictive a quad core system might be adequate and for that I'd suggest the Xeon E5-1620 v2 which runs at 3.7 / 3.9GHz and uses ECC 1866 RAM. The E5-1620 v2 at $300 (Superbiiz) is actually about $20 cheaper than the i7-4770K.
If you specify a budget for this system, it would be possible to make more specific suggestions.
For now, here's a kind of generic system idea worked out recently and revised>

TOTAL = $2,038
Again, a bit generic and at the lower end in terms of cost for this kind of system.
