Hi All,

I have bridging set up as per Gentoo KVM Wiki and it works fine after boot.
However, if I unplug and plug back in the network cable, the bridge fails to start. I don't see any failure messages in the logs, just nothing about bridge or br0.
When unplugging:
Code:

netplugd[4346]: eth0: state ACTIVE flags 0x00011043 UP,BROADCAST,RUNNING,MULTICAST,10000 -> 0x00001003 UP,BROADCAST,MULTICAST
netplugd[2481]: /etc/netplug.d/netplug eth0 out -> pid 2481
netplugd[4346]: eth0: state OUTING pid 2481 exited status 0
dhcpcd[5222]: br0: carrier lost


When plugging back:
Code:

netplugd[4346]: eth0: state INACTIVE flags 0x00001003 UP,BROADCAST,MULTICAST -> 0x00011043 UP,BROADCAST,RUNNING,MULTICAST,10000
netplugd[3022]: /etc/netplug.d/netplug eth0 in -> pid 3022
netplugd[4346]: eth0: state INNING pid 3022 exited status 0

and that's it, no DHCP, no br0 activation.

How do I reactivate bridge after plugging in the cable?

thanks,
alavov

(disclaimer: just an idea; I haven't tried it since I'm not at home...)

It's possible br0 is being treated as an interface subject to ifplug, if you have ifplugd installed. Possibly try adding
Code:
modules_br0="!plug"
to /etc/conf.d/net?

Thank you! Actually, it was the other way around - I needed to exclude eth0 from been "plugd"
Code:
modules_eth0="!plug"
, but the idea is the same :)
It works now.
