I'm using Packstack to install Openstack in a single node all-in-one. Everythings go well and i can deploy VM perfectly and ping/ssh to it. When i add a compute node, it seems that everything work. I can deploy a VM on the compute node and horizon show me as "Active", but i can't ping or ssh to it.

ovs-vsctl show of controller node:

Please help me, I need to solve it. If you need more infos ask without problem.

The virtual networks are implemented as VXLAN networks on br-tun. Strangely, the controller has two VXLAN peers 192.168.0.31 and 192.168.0.32, and the compute node has two peers 192.168.0.30 and 192.168.0.32. Why three addresses and two nodes? Do these addresses mean anything to you?

Also, what OpenStack version is that, and what answer files or packstack options did you use to set up the two nodes?

Sorry you are right. Controller node has IP 192.168.0.30. Compute node has IP 192.168.0.31. 192.168.0.32 it's an iP from a previous attempt with another computer no longer in use. The version of Openstack is Stein. Give me a minute and i'll load you my answer file.

An old, incorrect IP address in the database is certainly a problem that could cause all sort of strange things in your cloud. I would start from scratch, i.e. reinstall Centos, then Packstack, to prevent this from happening.

In the current situation, i can ping a vm in the controller node but i cannot ping one on the node compute.

This is my answer file (without password and comment), cause i can't post link:
