Hi qemu team, I just discovered that qemu now offers kvm support, so I decided to compare it to qemu-kvm.
I'm running the latest git versions of both programs on an AMD64 host running the latest kernel from Linus.git. The guest is Windows 7 on a qcow2 disk image and one kvm64 cpu. Using the same qcow2 image for both qemu and qemu-kvm, I find that qemu-kvm boots to the Win7 login prompt in 25 seconds, but qemu with kvm enabled takes about 45 seconds. Is this an expected outcome, or must I be doing something wrong with qemu? BTW, I tried reverting the qcow2 patch being discussed in another thread but it made no difference. Perhaps there's not much writing to disk during bootup? Thanks!
