I noticed that the qemu-kvm binaries generated from the KVM git/sources are considerably faster then using the original qemu git/sources. No, I have added “-machine …,accel=kvm” as well as the “–enable-kvm” switch upon building and execution time.
So, it seems that the KVM project does something extra. I have read on the KVM site that their code is ported back into the main stream QEMU development. I don’t no when, but the qemu main stream is too slow to use it in daily circumstances.
It might be possible that I am missing something, but can anybody explain the above situation?
