RHBA-2012:0727 - 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:

  • Due to a locking problem in one of the routines involved in the migration process, migrations could become unresponsive, for example, when repeatedly migrating a domain between two nodes. The locking problem has been fixed with this update, and migrating a guest is now successful in this scenario. (BZ#826639)

  • Closing a file descriptor multiple times could, under certain circumstances, lead to a failure to execute the qemu-kvm binary. As a consequence, a guest failed to start. A patch has been applied to address this issue, so that the guest now starts successfully. (BZ#827047)

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.

This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258
