<div>do you see sent and received packets on the vlan? I would suspect that you actually don't have the vlans trunked on the ports so the packets aren't making it across the switch.

<br>
This sounds like it might be working properly. In VLAN mode, all<br>
instances are connected to one of the project vlans. The .1 address<br>
(gateway, dhcp, etc) exists on an interface on the nova-network node<br>
(or one of them, in the case that you are running multiple. This<br>
interface is bridged to a tagged interface on the appropriate vlan<br>
tag. On the nova-compute nodes, a vnet interface for the instance is<br>
bridged to the vlan tagged interface. On the compute node, there isn't<br>
an IP interface on this network, so the private IP for instances isn't<br>
reachable, even if the instance is running on the same node.<br>
<br>
The canonical test for correct network function is if an instance is<br>
reachable via ping from the nova-network server that is currently<br>
serving the instance's project network.<br>
