libvirt bug fix update

Updated libvirt packages that fix two bugs are now available for Red Hat
Enterprise Linux 6.

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.

This update fixes the following bugs:

* If the user attempted to connect locally as a non-root user to the libvirtd
daemon (using "qemu:///user"), the ".libvirt" directory was not created in the
home directory. As a consequence, non-root users failed to use libvirt. This
update ensures that the directory is created, and libvirt now works as expected
for non-root users. (BZ#798177)

* The localtime_r() function used in the libvirt code was not async signal safe,
which caused child processes to enter a deadlock when attempting to generate a
log message. As a consequence, the virsh utility became unresponsive. This
update applies backported patches and adds a new API for generating log time
stamps in an async-signal safe manner. The virsh utility no longer hangs under
these circumstances. (BZ#798906)

All users of libvirt are advised to upgrade to these updated packages, which fix
these bugs. After installing these updated packages, libvirtd must be restarted.
Use the "service libvirtd restart" command for this update to take effect.

Before applying this update, make sure all previously-released errata relevant
to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red
Hat Network to apply this update are available at
