When i want to delete my test bridge, using: ifconfig eth0 down ifconfig eth1 down ifconfig br0 down brctl delif br0 eth0 brctl delif br0 eth1 brctl delbr br0 i get this error message from the kernel on the console: unregister_netdevice: waiting for br0 to become free.

During my attempts to get the latest bridge networking model working on my system, I often invoked ''network-bridge stop'' with total failure.

...thod that can be done from the virsh interface. Thanks Juerg! 1) down the vnetX interface from the host node ip link show dev vnetX ip link set down vnetX ip link show dev vnetX And if using bridged networking, you have one more option. 2) remove the vnetX interface from the bridge brctl delif <bridge_int> vnetX Certainly downing the interface using either Juerg's solution via virsh or mine via iproute2 tools is most ideal since it's easier/simpler to reinstate. You can use ifconfig if you prefer it over ip tools, but enjoy those tools and syntax while it remains! [0] ;-...
