Linux KVM Continues Offering Much Better Performance Than VirtualBox

With the release earlier this month of Oracle VirtualBox 6.0, besides running some benchmarks of its VMSVGA 3D graphics support, I also ran some basic benchmarks to see how a similarly configured VM under both VirtualBox 6.0 with Linux KVM setup via virt-manager would compare for performance as we hit the end of 2018. This quick round of Linux virtualization tests was done on the AMD Ryzen Threadripper 2990WX system.
