Hi,
I've tested the guest Linux using UnixBench 5.1.2. The platform is:
* Intel's Core Due CPU with 2 cores, 2GB RAM
* CentOS 5.2 as the dom0 Linux, i.e., the host Linux for KVM
* CentOS 5.2 as the guest Linux, i.e., the Linux running on the
virtual machine provided by Qemu
The first set of results is for Luvalley, and the second one is for
KVM. As the result, Luvalley's guest Linux is 20% ~ 30% faster than
KVM's guest! It is very surprise to me. I had through Luvalley's guest
should be the same performance as KVM's.
Luvalley's result:

> Subject: Luvalley-2 has been released: running KVM below any operating system
>
> Luvalley is a Virtual Machine Monitor (VMM) spawned from the KVM
> project. Its part of source codes are derived from KVM to virtualize
> CPU instructions and memory management unit (MMU). However, its
> overall architecture is completely different from KVM, but somewhat
> like Xen. Luvalley runs outside of Linux, just like Xen's
> architecture. Any operating system, including Linux, could be used as
> Luvalley's scheduler, memory
> manager, physical device driver provider and virtual IO device
> emulator. Currently, Luvalley supports Linux and Windows. That is to
> say, one may run Luvalley to boot a Linux or Windows, and then run
> multiple virtualized operating systems on such Linux or Windows.
>
> If you are interested in Luvalley project, you may download the source
> codes from
> http://sourceforge.net/projects/luvalley/
>
> This release (i.e., luvalley-2) updated Qemu in both Linux and
> Windows. So the limitations of the previous release (i.e., luvalley-1)
> have been partially eliminated. For example, the Qemu in Windows
> allows to create disk images and install gueest operating systems.
>
> This release has 4 tarballs:
>
> * luvalley-2.tgz: this is the source codes of the kernel part of
> Luvalley, which should be compiled in Linux. It is running below any
> operating system to provide virtualization extension for Intel's
> X86/32 computers. See the README file of the tarball for how to
> compile and run Luvalley.
>
> * qemu-linux.tgz: this is the source codes of the modified Qemu for
> running virtualized guest OSs in Linux. It is derived from Qemu of
> KVM-83. See the README file of the tarball for how to compile and run.
>
> * qemu-windows.tgz: this is the source codes of the modified Qemu for
> running virtualized guest OSs in Windows. It is derived from
> Qemu-0.10.2. See the README file of the tarball for how to build and
> run.
>
> * WindowsXP-Bins.rar: this is the pre-compiled binaries for running
> in Windows XP. It should be uncompressed in Windows XP operating
> system with WinRAR or other programs that supports .rar format. See
> the README file of the package for how to install and run in Windows
> XP.
