First, or second?
The latter. I asked this question several weeks ago. The response was that it "would be nice" for KVM to support non-VMX machines, but that it wasn't a priority in any way for any of the current developers. My understanding is that the paravirtualisation support that Ingo wrote is purely for performance purposes, bypassing the hardware emulation layer in qemu and going directly to the host VM's device layer.
