RHEA-2011:0060 - Product Enhancement Advisory

Topic

Updated libvirt packages that upgrade the libvirt library to upstream
version 0.8.2, add sVirt support, and fix a number of bugs and add
various enhancements are now available for Red Hat Enterprise Linux 5.

Description

The libvirt library is a C API for managing and interacting with the
virtualization capabilities of Linux and other operating systems. In
addition, libvirt provides tools for remotely managing virtualized
systems.

These updated packages upgrade the libvirt library for Red Hat
Enterprise Linux 5 to upstream version 0.8.2, which contains a large
number of enhancements and bug fixes over the previous version.
Importantly, with this libvirt update, Red Hat Enterprise Linux 5.6 now
provides support for sVirt, which brings mandatory access control to
the KVM hypervisor. (BZ#544303)
