I just tried on my desktop, woot it's super fast!

read the hypervisor part of the lwn article: https://lwn.net/SubscriberLink/644675/5be656c24083e53b/

quote: "With kvmtool, we no longer need a BIOS or UEFI; instead we can jump directly into the Linux kernel. Kvmtool is not cost-free, of course; starting kvmtool and creating the CPU contexts takes approximately 30 milliseconds."

Anyone know what they might be doing for the speed increase?

Seeing as it's Intel I might guess that they either have extra instructions in the instruction set they know about or other optimizations that they know to look for. Seeing as they only support 4th generation and E5 v3... it wouldn't surprise me.
