Thanks Marcelo

If libvirt-bin is started, then you have the bridge interface:

$ ifconfig virbr0
virbr0    Link encap:Ethernet  HWaddr 00:00:00:00:00:00
          inet addr:192.168.122.1  Bcast:192.168.122.255  Mask:255.255.255.0
          inet6 addr: fe80::200:ff:fe00:0/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:31 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:0 (0.0 b)  TX bytes:5135 (5.0 KB)

Stop it:

~$ sudo /etc/init.d/libvirt-bin stop
 * Stopping libvirt management daemon libvirtd                           [
OK ]

Problem, its still up:

$ ifconfig virbr0
virbr0    Link encap:Ethernet  HWaddr 00:00:00:00:00:00
          inet addr:192.168.122.1  Bcast:192.168.122.255  Mask:255.255.255.0
          inet6 addr: fe80::200:ff:fe00:0/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:31 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:0 (0.0 b)  TX bytes:5135 (5.0 KB)


Try and start it:

$ sudo /etc/init.d/libvirt-bin start
 * Starting libvirt management daemon
libvirtd                                  libvir: QEMU error : cannot create
bridge 'virbr0' : File exists
Failed to autostart network 'default': cannot create bridge 'virbr0' : File
exists

Not sure if this helps. I have two laptops with the same configuration. I.e.
I started with the same version from the ppa repo. They have recently been
upgraded. They never used to have the bridge problem before the package
upgrades. Something must have changed. I must say that you only notice the
brigde issue if you are restarting the service at the command line. When its
all working and you boot up, you dont notice it.
