Ubuntu 12.04 Oracle VM VirtualBox Intel Core i7-3960X benchmarking of various Ubuntu 12.04 LTS virtualization options with the Precise Linux 3.2 kernel. Testing of bare metal, Xen, KVM, and Oracle VM VirtualBox virtualization methods from this Intel Sandy Bridge Extreme Edition system that was running in the same configuration for the duration of testing. This Linux virtualization benchmarking is for a future article on Phoronix.com.
