Involved Projects and Packages
Virtual Machine Viewer provides a graphical console client for
connecting to virtual machines. It uses the GTK-VNC widget to provide
the display, and libvirt for looking up VNC server details.

Xen is a virtual machine monitor for x86 that supports execution of
multiple guest operating systems with unprecedented levels of
performance and resource isolation.
This package contains the Xen Hypervisor. (tm)
Modern computers are sufficiently powerful to use virtualization to
present the illusion of many smaller virtual machines (VMs), each
running a separate operating system instance. Successful partitioning
of a machine to support the concurrent execution of multiple operating
systems poses several challenges. Firstly, virtual machines must be
isolated from one another: It is not acceptable for the execution of
one to adversely affect the performance of another. This is
particularly true when virtual machines are owned by mutually
untrusting users. Secondly, it is necessary to support a variety of
different operating systems to accommodate the heterogeneity of popular
applications. Thirdly, the performance overhead introduced by
virtualization should be small.
Xen uses a technique called paravirtualization: The guest OS is
modified, mainly to enhance performance.
The Xen hypervisor (microkernel) does not provide device drivers for
your hardware (except for CPU and memory). This job is left to the
kernel that's running in domain 0. Thus the domain 0 kernel is
privileged; it has full hardware access. It's started immediately after
Xen starts up. Other domains have no access to the hardware; instead
they use virtual interfaces that are provided by Xen (with the help of
the domain 0 kernel).
In addition to this package you need to install the kernel-xen, xen-libs
and xen-tools packages to use Xen. Xen version 3 and newer also supports
running unmodified guests using full virtualization, if appropriate hardware
is present.

Maintenance devel / staging area for virtualization packages in openSUSE 12.1
Xen Hypervisor for PVH support on x86_64 only.
Technical Preview
Support is limited to the following:
PVH guest support
Xl/libxl based Xen management toolstack
Live migration of guests
Guests running in cpupools using the credit scheduler
XenStore running as a stubdom
Dom0 running in PVH mode
This project Does Not support the following:
PV guest
HVM guest
QEMU based backend (so no Xen-enabled qemu needed at all)
Libvirt (no 'virsh' management)
PCI passthrough
Packages being prepared for inclusion in the main Virtualization project are staged here.
QEMU is a quick emulator, using dynamic translation (TCG). In support of virtualization, it also serves as a frontend for KVM and as a backend for Xen device emulation.
Note that this package is produced using a Git based workflow. Please refer to README.PACKAGING before making modifications.
Tests and supporting packages related to testing Virtualization infrastructure.
