I’ve been a fan of KVM for quite some time, and gave a talk on it a while back. The KVM design always made sense to me, and I tossed Xen out the window the minute I started using it. Today I was pleasantly surprised to see that several folks from Joyent ported KVM to Illumos! This is way cool, and I can’t wait to give this a spin! Hopefully libvirt integration and various goodies are there. :)
