Thread-topic: Networking issue with VlanManager and Floating IPs

Folks,

We are using Essex for our multi-host OpenStack deployment with Vlan Manager.
All the private IPs are working as expected in a multi-tenant scenario but the problem that we are seen is with Floating IPs.

We have three tenants,  all of them are able to use  Floating IPs and then VMs are reachable from the public network but the inter VMs connectivity by private IPs is totally lost. Once we dissociate the Floating IPs to the corresponding VMs, the connectivity is back. The odd part is that we are seeing this behavior in just two of the three tenants that we have tested so far.

Is anyone aware of any bug or misconfiguration in Nova-network that could explain this behavior? We will be running more tests and we can provide detailed information of our environment if needed.

Thanks for your help,

Edgar
