RHBA-2012:1095 - libvirt bug fix update

Synopsis

libvirt bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated libvirt packages that fix two bugs 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.

This update fixes the following bugs:

• Previously, repeatedly attaching and detaching a PCI device to a guest domain could cause the libvirt daemon to terminate unexpectedly. The erroneous structure free operation at the root of this bug has been fixed and repeated attach and detach actions of a PCI device now work as expected. (BZ#836916)

• On certain NUMA architectures, libvirt was failing to process and expose the NUMA topology, possibly leading to performance degradation. These updated packages now correctly parse and expose the NUMA topology on such machines and make the correct CPU placement, thus avoiding the performance degradation. (BZ#836919)

• When using the sanlock daemon for locking resources used by a domain, if such a resource was read-only, the locking attempt failed. Consequently, it was impossible to start a domain with a CD-ROM drive. This bug has been fixed and sanlock can now be properly used with read-only devices. (BZ#838819)

All users of libvirt are advised to upgrade to these updated packages, which fix these bugs.

Solution

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