Hi
Recently I’ve deployed a virtualisation server based on OpenSuse 12.3, kvm and libvirt. It was a kiwi-defined system, which I already used for some time on other hardware (but with other packet versions maybe), so I didn’t expect any surprises. However, when I configured the bridging interface and rebooted, my system stuck for a 300 seconds timeout for
unregister_netdevice: waiting for br0 to become free. Usage count = 1
Eventually it rebooted alright, but waiting for 5 minutes for each reboot is insane. Same thing happens if I try ti stop/restart network.service or bridge itself. What has been done to solve the issue: I’ve updated the kernel, disabled the ipv6 in yast, re-wrote config files by hand ( actually, copied them from the working server), but nothing helped on regular basis. Once in a time, my system bypasses this problem, if I reboot really fast after initial boot. By if it stays up a little- hello, 5 minute ping timeout.
My network configs:
cat ./ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
IPADDR=0.0.0.0
ONBOOT=yes
STARTMODE=hotplug
TYPE=Ethernet
USERCTL=no
IPV6INIT=no
cat ./ifcfg-br0
STARTMODE=‘auto’
BOOTPROTO=‘static’
USERCONTROL=‘no’
IPADDR=‘192.168.0.189/19’
BRIDGE=‘yes’
BRIDGE_PORTS=‘eth0’
BRIDGE_AGEINGTIME=‘300’
BRIDGE_FORWARDDELAY=‘0.1’
BRIDGE_HELLOTIME=‘2’
BRIDGE_MAXAGE=‘20’
BRIDGE_PATHCOSTS=‘19’
BRIDGE_STP=‘off’
