Re: Rebooted, now can't ping my guest

 

There is a known bug for the network bridges, when rebooting :
https://bugs.launchpad.net/quantum/+bug/1091605

Try to delete/recreate your br-int/br-ex and then restart openvswitch_plugin/l3/dhcp agents, it should fix the issue.

In my case, it actually appears that my vms aren't up-- the instances panel says they are up, but looking at the console, it appears they aren't getting an IP address. This is a new instance:

It looks like it made an OVS port, though. This is on the compute node, openvswitch-agent.log:

I supposed it should be getting address via DHCP from quantum-dhcp-agent on the network node? It was running, nothing regarding this MAC in the logs. I restarted quantum-dhcp-agent and rebooted, no change.

In fact, I got two CirrOS vms up, logged on the console and manually IPed them (10.5.5.10/24 <http://10.5.5.10/24> and 10.5.5.11/24 <http://10.5.5.11/24>), and they can't ping each other. I would expect them to, right? They should both be connected to OVS switch br-int, right?

Any pointers?
