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>hth<br>-nld<br><br>On Wed, May 30, 2012 at 5:42 PM, Vijay <<a href="mailto:vijayrg@yahoo.com" ymailto="mailto:vijayrg@yahoo.com">vijayrg@yahoo.com</a>> wrote:<br>> Hello,<br>> I am trying install Essex in VLAN mode on multiple compute
