Subject: [Openstack] Openstack networking usecase

Hello All,

I need your help in following networking scenario:

  *   I bring up 2 VM's in a compute Node via Openstack Controller Dashboard
  *   these two VM's below to same virtual Network
  *   Each VM gets an virtual IP address
  *   SCENARIO: Is it possible that, each virtual IP is given assigned an access-vlan and pass the vlan traffic to outside physical/real port that is connected to Trunk port of an external switch?
  *   VM1 and VM2 shouldnt talk to each other without passing through the trunk port

VM1 gets a virtual IP address lets say<>., how to assign a access vlan, lets say vlan 10.,

VM2 gets a virtual  IP address lets say<>.,  how to assign a access vlan, lets say vlan20(access port)

My physical interface of the compute node is ETH0., connected to trunk port of a switch.,

VM1 and VM2 shouldnt talk to each other until and unless they pass through the trunk and gets the packet processed further by an external l3 switch..

does it require an explicit configuration of openVswitch ??
