I found out earlier today that kqemu is now GPLed. I think this has the potential of helping out the KVM team by (hopefully) taking some of the tricks that helps kqemu get almost as good performance (on some benchmarks) as KVM w/ the hardware vitualization extensions.
Here I am running Ubuntu (aside: next time I pave over I am going back to Debian), and I want to have kqemu running WinXP and Suse 10. But really… I just wanted to try kqemu on my poor desktop that lacks the virtualization extensions.
