hi all !

I wrote an article about different types of Virtualization here:
http://www.violtan.com/ae/virtualization.html

This article describes 4 stages of Virtualization: Emulation, Full
Virtualization, Para-Virtualization and OS-level Virtualization.

I believe that openSUSE must excel at all types of Virtualization.

openSUSE did some progress in terms of Virtualization: namely we
consider integrating VirtualBox into openSUSE.

Until now openSUSE is too focused on Xen. Xen-centric approach is bad.
We need a wide array of technologies in openSUSE. Qemu and DOSbox
emulators are fortunately already included. openSUSE 10.3 kernel also
support USB-FS (allows for using USB in guest VMs) , KVM
(Qemu-accelerator) and VMI (kernel paravirtualization) each of these
technologies improve Virtualization further.

One thing we still lack is OS-level Virtualization: such as OpenVZ -
this technology allows for partial virtualization at speeds
unreachable for Xen.

The most serious problem with bringing OpenVZ to openSUSE is: their
project is too RedHat-centric. This is a serious issue, because all of
their documentation, packages, utilities, templates and even
source-code patches are RedHat-centric, and none of their software
work on SUSE. I have failed to bring this technology to openSUSE. I
hope there are SUSE developers around who can break their RedHat
monopoly and bring this excellent technology to SUSE.

Again: I vote for wide array of Virtualization solutions in openSUSE
(instead of being Xen-centric).

I have several more interesting ideas considering Virtualization, such
as building a bridge between UnionFS and OpenVZ.

Who are the people responsible for virtualization efforts in openSUSE ?
