We have an existing xenserver environment I have recently inherited. We have multiple xenserver vlans working that can all talk to each other. I am now trying to set up another network and cannot seem to get the VM's on the same physical host communicating with each other.

We are running a citrix virtual distributed switch, all existing networks can talk to each other but my newly created one does not work. Every setting I can find is identical to those previously configured.

I created a new interface in XenServer, tagged with VLAN 16 (a new vlan). I created an interface on our Cisco ASA 5510 as well tagged as VLAN 16. Do I need to configure this elsewhere (on the physical switch, etc)?


If you're configuring a "Tagged" Network on XenServer, then this implies that it corresponds to a physical NIC which is plugged into a trunk port. Is this case? If the port on the switch is an access port with only a single VLAN, then you shouldn't be tagging anything on XenServer.

Posting screenshots of your NIC and Networking pages from XenServer would be great, along with some more detail on your network topology.

Also, there is no XenServer 6.5!
