RHBA-2016:1261 - Bug Fix Advisory

Topic

Updated libvirt packages that fix one bug are now available for Red Hat Enterprise Linux 6 Advanced Update Support.

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 bug:

• Prior to this update, migrating a virtual machine failed when the libvirtd service attempted to use a transmission control protocol (TCP) port that was already in use. Now, libvirtd ensures that the port it chooses from the migration TCP port range is not used by another process. In addition, it is possible to predefine a custom migration TCP port range in case the default range conflicts with other services. (BZ#1340479)

Users of libvirt are advised to upgrade to these updated packages, which fix this bug. After installing the updated packages, libvirtd will be restarted automatically.
