Back in January of 2007 we had looked at Linux Virtualization
Performance as we had compared a running native OS (at that time, Fedora
Core 6) against the same operating system running as a virtualized guest
OS using Xen, QEMU with the (once closed-source) kqemu kernel module,
and then KVM. In this testing we had found that KVM had performed well
and won a number of the tests, but it wasn't the clear winner nor it had
won by a substantial margin. However, the Kernel-based Virtual Machine
had premiered with the Linux 2.6.20 kernel and it has matured quite a
bit over the past year and a half since its christening. With that said,
we are in the process of conducting new Linux virtualization benchmarks
to see how these various implementations compare today. While the full
comparison isn't yet ready, due to much interest surrounding Linux
virtualization on desktops and servers, this morning we are publishing
some initial benchmarks from the Phoronix Test Suite when running Ubuntu
8.04 LTS as the host OS and then running it as the guest operating
system with hardware-based acceleration through KVM.
Check out the results
