Topic

Updated libvirt packages that fix multiple bugs and add various enhancements are
now available for Red Hat Enterprise Linux 6.

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 remote management of virtualized systems.

These updated libvirt packages include numerous bug fixes and enhancements.
Space precludes documenting all of these changes in this advisory. Users are
directed to the Red Hat Enterprise Linux 6.2 Technical Notes for information on
the most significant of these changes:
