KVM, QEMU, and kernel project management

The server virt market will be saturated in a couple of years if not sooner.

Are there more desktops in the world or servers?

If desktop virtualization were built in and the way you ran any OS, which is what client hypervisors are about, it will be a much bigger market.

I'm not saying server virtualization is going away or anything... just that it is going to get much bigger on the desktop.
