Trying to get VLANs working inside CTs on Proxmox 2.3 and having no luck. In order to remove as many variables as possible, I am not traversing an external switch, merely trying to connect to CTs on the same host to each other across a new VLAN.
First, I added a new veth to each CT (using one here as an example):

Then, I configured the new interface in the CTs by creating /etc/network/interfaces.tail as follows
Then reboot the CT, but I don't see the new IP in the routing table and also lose connectivity through my existing interface (can ping myself, but not the router):
Now rename the file and reboot:
And the connectivity is back:
Any suggestions?
thanks~
