Why 2.6.26, specifically if you seem to have no customized bits?
Starting with a pre-historic kernel for a new project is hardly ever a
good choice.

That kernel is 2 years old, last version is 1.5 years old, and kvm was
still quite young into mainline at that time. There is a good chance you
may hit some bug that was fixed since then.

kvm-kmod builds down to 2.6.24, but it is likely only tested down to
2.6.27. And you will miss quite a few relevant performance optimization
due to limitations of 2.6.26.
