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.
make sure you build qemu with --enable-io-thread. Also, what's your
full command line?

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!
