<div dir="ltr">Hi All,<div><br></div><div>I'm new to the list, but have been recommended by a colleague that i post my issue here incase any of you can help. I've been a linux user since the mid 90's and administrating for the last 4-5 years or so.<br clear="all">
<div><br></div><div>my issue is with an Openstack (havana) install on Ubuntu 13.10 in the following all-in-one configuration:</div><div>controller on eth0 (192.168.1.90)</div><div>compute on eth0:1 (192.168.1.91)</div><div>
nova-network is set to create bridge br100 on eth0:1 for the VM's flat network (<a href="http://10.0.0.0/24">10.0.0.0/24</a>)</div><div><br></div><div>The problems i'm having so far are:</div><div>1) on bootup, br100 seems to come up before eth0 is ready, and fails</div>
<div>2) on bootup, eth0 (Realtek RTL8111/8168/8411) is in a failed state (ifconfig shows no configured IP's) and requires module reinsertion (rmmod r8169 ; modprobe r8169) before it starts working</div><div>3) restarting nova-network after fixing eth0 breaks network connectivity until i manually remove eth0:1 from the bridge (brctl delif br100 eth0:1) and restart the networking service. Setting up the bridge on eth0 also causes the same failure. </div>
<div><br></div><div>i'm not particularly concerned with #1 and #2 as they can possibly be fixed with init ordering/dependencies, or at worst, rc.local hacks.</div><div><br></div><div>#3 is doing my head in, and unfortunately i havent played with bridging enough to know what normal configuration / behaviour should be. </div>
<div><br></div><div>default routing is correct (default 192.168.1.1 0.0.0.0 UG 0 0 0 eth0) and working.</div><div><br></div><div>so my questions to you linux/openstack guru's out there:</div>
<div>1) can you bridge to a virtual interface? (google finds no similar examples)</div><div>2) nova-network is handling the configuration of br100, but it has no IP. is this correct?</div><div>3) do i need to add routing for br100, or will the default gateway setup be enough?</div>
<div><br></div><div>i'm happy to provide config or output if it will help debug.</div><div><br></div><div>any input would be greatly appreciated!</div><div><br></div><div>cheers,</div><div>rowy.</div><div><br></div>-- </div>
