description: When I add my virtual ethernet device on my host to a bridge I lose network access to the host (but the guest network starts working). When first added I get the following in dmesg: Quote: device veth101.0 entered promiscuous mode type=1700 audit(1286208967.671:29): dev=veth101.0 prom=256 old_prom=0 auid=4294967295 ses=4294967295 br0: port 2(veth101.0) entering learning state br0: port 2(veth101.0) entering learning state At this point the network still works. After a short while (a few seconds) I get this message: Quote: br0: topology change detected, propagating br0: port 2(veth101.0) entering forwarding state at which point the network starts working. ifconfig on the host: Quote: br0 Link encap:Ethernet HWaddr 00:18:51:4E:9C:93 inet addr:94.23.156.36 Bcast:94.23.156.36 Mask:255.255.255.255 inet6 addr: fe80::ff:fe76:1e61/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:9583 errors:0 dropped:0 overruns:0 frame:0 TX packets:7302 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1459708 (1.3 MiB) TX bytes:2762327 (2.6 MiB) eth0 Link encap:Ethernet HWaddr 02:00:00:76:1E:61 inet6 addr: fe80::ff:fe76:1e61/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:24725 errors:0 dropped:0 overruns:0 frame:0 TX packets:12050 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:16737073 (15.9 MiB) TX bytes:3246339 (3.0 MiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:756 errors:0 dropped:0 overruns:0 frame:0 TX packets:756 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:83246 (81.2 KiB) TX bytes:83246 (81.2 KiB) venet0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:10.0.0.1 P-t-P:10.0.0.1 Bcast:0.0.0.0 Mask:255.255.255.255 UP BROADCAST POINTOPOINT RUNNING NOARP MTU:1500 Metric:1 RX packets:387 errors:0 dropped:0 overruns:0 …
