Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.

https://bugzilla.redhat.com/show_bug.cgi?id=1125755 reported that a stray bridge device was left on the system when a libvirt network failed to start due to an illegal iptables rule caused by bad config. Apparently the reason this was happening was that NetworkManager was noticing immediately when the bridge device was created and automatically setting it IFF_UP. libvirt would then try to setup the iptables rules, get an error back, and since libvirt had never IFF_UPed the bridge, it didn't expect that it needed to set it ~IFF_UP before deleting it during the cleanup process. But the ioctl(SIOCBRDELBR) ioctl will fail to delete a bridge if it is IFF_UP. Since that bug was reported, NetworkManager has gotten a bit more polite in this respect, but just in case something similar happens in the future, this patch switches to using the netlink RTM_DELLINK message to delete the bridge - unlike SIOCBRDELBR, it will delete the requested bridge no matter what the setting of IFF_UP. |

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
