I validated a recent deployment with noVNC 1.0. It was necessary to change nova's '[vnc] novncproxy_base_url' from '{address}/vnc_auto.html' to '{address}/vnc_simple.html'. This is because of commit 83391ffc in noVNC [1]. Once that was done, everything worked as expected. However, 'vnc_simple.html' only works with noVNC 1.0 while 'vnc_auto.html' only works with 0.6.x and prior. As such, we would need to upgrade noVNC _and_ update the configuration for all hosts at the same time to avoid breaking anything. This seems unrealistic.
There are two possible options here:
- Symlink 'vnc_auto.html' to 'vnc_simple.html', thus retaining backwards compatibility.
- Start using a different url, 'vnc.html?path=websockify', which apparently works with both 0.6 and 1.0. [2]
The first of these seems a more viable option in the short term. If we proceed with this, we'll also need a migration path to ensure we don't have to carry this patch forever. This will involve updating the values in 'nova.conf' to one of the above at upgrade time.
