RHBA-2012:0419 - 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:

• 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.

Solution
