libvirt-3.9.0-14.el7.2

The libvirt library contains 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, the libvirt service used the incorrect XML configuration when checking for a duplicate user alias. As a consequence, hot-plugging a device with a unique alias to a guest virtual machine in some cases failed with a "non unique alias" error message. With this update, libvirt uses the correct XML files for verifying the device alias, which prevents the problem from occurring. (BZ#1554928, BZ#1554962)

* Prior to this update, if the "interface type='hostdev'" configuration was used for a guest virtual machine, booting the guest in some cases failed due to a validation error. With this update, the libvirt service has been fixed to ignore hostdev duplicates in the XML configuration. As a result, the guest boots correctly in the described scenario. (BZ#1558655)

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