Description

This release of libvirt fixes a minor security problem with extraneous iptables rules being added when an externally managed network (new feature in 0.9.4) exists, along with several bugfixes. Another important change in this release is code to automatically convert guest definitions containing the deprecated 'fedora-13' machine type over to 'pc-0.14' - support for the 'fedora-13' machine type will be removed from qemu in Fedora 17, so all guests will need to be reconfigured before that time; the code in this update handles the reconfiguration automatically.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
