“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…”
