Subject: [Qemu-devel] qemu-kvm faster that qemu?
Date: Wed, 25 Aug 2010 12:37:51 -0700	[thread overview]
Message-ID: <i53ren$56d$1@dough.gmane.org> (raw)

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!
