I am probably being very dense here. I cannot see how to create a virtual chassis!
I have been following the "develop" branch, but I don't think I applied any updates while 2.3 beta was underway (I *think* I updated to 2.2.10, certainly to 2.2.9). I have now updated to the tip of 'develop': the top commit is
commit 970759ed8ba786a38e599e2160e9e7e13671f487
Date: Mon Feb 26 14:19:38 2018 -0500
Release v2.3.0
After doing the upgrade, the virtual chassis feature appears under the Devices menu, but there is no "+" button next to it.
If I select Virtual Chassis from the menu, which takes me to /dcim/virtual-chassis/, I get an empty list of virtual chassis, but no Add button.
If I manually enter /dcim/virtual-chassis/add/ in the URL bar, I get a HTTP 405 error.
I am logged in as "admin", and otherwise everything seems fine - for example I can happily add a new Device. (But creating or editing a device does not show any options relating to VCs either).
I even looked in the source: netbox/templates/dcim/virtualchassis_list.html doesn't appear to have an add_button, and netbox/templates/inc/nav_menu.html doesn't have Add or Import buttons next to Virtual Chassis.
Thanks... Brian.
