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.
