http://bugzilla.suse.com/show_bug.cgi?id=954329 Bug ID: 954329 Summary: Purely virtual bridge breaks networking Classification: openSUSE Product: openSUSE Tumbleweed Version: 2015* Hardware: Other OS: Other Status: NEW Severity: Major Priority: P5 - None Component: Network Assignee: bnc-team-screening@forge.provo.novell.com Reporter: lmb@suse.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Take a purely virtual bridge (to be used for VMs) with a static network configuration: # cat /etc/sysconfig/network/ifcfg-br0 STARTMODE='auto' BOOTPROTO='static' BRIDGE='yes' BRIDGE_PORTS='' BRIDGE_FORWARDDELAY='0' BRIDGE_STP='off' IPADDR='172.16.1.1/24' enp0s25 is the local, normal ethernet interface which is working fine: 2: enp0s25: mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000 Now: # ifup br0 # ip link 2: enp0s25: mtu 1500 qdisc pfifo_fast master br0 state UP mode DEFAULT group default qlen 1000 link/ether 28:d2:44:df:33:18 brd ff:ff:ff:ff:ff:ff 9: br0: mtu 1500 qdisc noqueue state UP mode DEFAULT group default qlen 1000 link/ether 28:d2:44:df:33:18 brd ff:ff:ff:ff:ff:ff It seems that the scripts use the ethernet interface as the *default* value for BRIDGE_PORTS, which obviously then breaks networking. (If I had wanted a slaved network device, I'd have configured one.) brctl addbr br0 ; ip a add dev br0 172.16.1.1/24 ; ip link set br0 up creates the desired configuration just fine and is what I'd have expected given the configuration file. -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.suse.com/show_bug.cgi?id=954329 http://bugzilla.suse.com/show_bug.cgi?id=954329#c2 --- Comment #2 from Lars Marowsky-Bree --- (In reply to Pawel Wieczorkiewicz from comment #1)

...

Have you had br0(enp0s25) running before?

Yes, I had that configuration in the past. (And then figured out that that didn't work as I needed it to, and removed the enslaved device from the configuration.)

...

If so have you ifdown all (or ifdown br0 _and_ ifdown enp0s25) the interface before ifup br0 with new config?

Yes. I restarted both all network interfaces, and wickedd. Karol eventually suggested I try: # rm /var/run/wicked/state-* which made the problem go away, and it's now behaving as expected. I didn't save the state-* files for debugging though :-( -- You are receiving this mail because: You are on the CC list for the bug.
