Hi, Please check your ‘/etc/nova/nova.conf’. After installing cinder, you need to configure some cinder settings in nova.conf. Please follow the below link to install and configure cinder in controller node: https://github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/blob/OVS_SingleNode/OpenSta

the uneven ssh performance is strange - maybe learning on the tunnel mesh is not stablizing. It is easy to mess it up by giving a wrong local_ip in the ovs-plugin config file. Check the tunnels ports on br-tun with 'ovs-vsctl show'. Is each one using the correct IPs? Br-tun should have N-1 gre

ok, the tunnels look fine. One thing that looks funny on the network node are these untagged tap* devices. I guess you switched to using veths and then  switched back to not using them. I don't know if they matter, but you should clean them up by stopping everthing, running neutron-ovs-cleanup
