Wrong problem being solved
Nice stuff from the KVM team!
(I just wish that the vSwitch would get some love. Virtualization is useless for high-throughput network loads (audio/video transcoding, or other real time media flows) and quite honestly all the existing workarounds for it suck so badly I run screaming back to non-virtual hardware. 2017 and the best we have is SR-IOV+DPDK so long as you don't mind losing all your security groups?)
