Hey Totten25,

For connection between the hosts I use GRE:

[ml2_type_gre]
tunnel_type = gre

However I do have all 3 networks running over vlan tagged sub interfaces on a single nic. This is due to the number of ports I have free on the switch, the switch is not heavily loaded but it has allot of lab equipment plugged in. I did originally think that this was the issue however as it is working with a single compute node there is no reasoning for it not to work with multiple.

The output to those commands are below.
