To secure communications from the proxy server to the compute nodes using VeNCrypt authentication scheme. In a previous patch a TLS server certificate was deployed to compute nodes, this patch makes use of this same server cert for securing VNC sessions on compute nodes. It is recommended that this certificate be issued by a dedicated certificate authority solely for the VNC service, as libvirt does not currently have a mechanism to restrict what certificates can be presented by the proxy server. This has not been implemented to reduce complexity. In addition the noVNC proxy needs to present a client certificate so only approved VNC proxy servers can connect to the Compute nodes. The PKI role has been used to create a client certificate for the nova console nodes. Related Nova docs: https://docs.openstack.org/nova/latest/admin/remote-console-access.html To help with the transition from from unencrypted VNC to VeNCrypt, initially compute nodes auth scheme allows for both encrypted and unencrypted sessions using the variable `nova_vencrypt_auth_scheme`, this will be removed in future releases.
