[Qemu-devel] Luvalley-2 released: enable Qemu to utilize hardware virtualization extensions on arbitrary operating system

[Xiaodong Yi]

Luvalley is a Virtual Machine Monitor (VMM) with the architecture
somewhat like Xen. It runs below the operating system, and depends on
Qemu to run multiple virtualized operating systems. Luvalley has the
following distinguished features:

 * In theory, any operating system, e.g., Linux, Windows, BSD, etc.,
could run on top of Luvalley to serve as its scheduler, memory
manager and physical device driver provider. Luvalley needs no
modification on such OS. Moreover, Luvalley takes over no hardware and
device other than CPU and MMU. So it has rather good hardware
compatibility.

 * Excellent cooperation with Qemu. Luvalley and Qemu could benefit
each other. Qemu provides Luvalley an excellent virtual IO device
emulator to run multiple virtualized operating systems simultaneously.
And Luvalley enables Qemu to utilize hardware virtualization
extensions on arbitrary operating system.

If you are interested in Luvalley project, you may download Luvalley's
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.

You really should put some kind of version or date into your filenames.
It is very annoying later to try and figure out which version of a file
you have when the name is always the same.

Hi,

In theory, OpenBSD should be able to run on top of Luvalley, provided
that your computer has installed Grub to load Luvalley. After Luvalley
was loaded by Grub, you may choose to boot OpenBSD. It should work.

I did not test Qemu in OpenBSD yet. Maybe there was something wrong,
but I think it should be easy to fix. So please send me a message for
any progress.

As for repository of the source codes, it will be built in the short future.

Thanks for your attention and welcome all feedback.

Regards,

Xiaodong Yi
