[nova]vnc and spice used together in openstack

25 May 2023

      Hi,

When using the console, we enabled both nova spicehtml5proxy and nova novancproxy on the controller node, and enabled vnc and spice on compute1 and compute2, respectively. We found that there was a problem with the coexistence of the two, The log is as follows.

I don't know why there is an appeal issue or what special mechanism OpenStack has for the console. I can only choose one. I hope you can help us. Thank you very much.
