RHBA-2012:1000 - 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:

• 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#827050)

• Libvirt 0.9.10 has added support for keepalive checking to detect broken connections between the client and the server. However, due to bugs in the implementation this could have caused a failure of service and disconnection, for example, during parallel migrations. The keepalive support is now disabled by default and random disconnections no longer occur. (BZ#832184)

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
