Open Stack

Thanks for the info, looks like this is xen only stuff,  not sure whether
this is needed for now or we can remove it
remote_consoles seems related to some general console but not specific to
xvp,

so https://review.openstack.org/459266 just for some info to api reader and
if we are sure xen don't use it any more, we can remove it totally.

Best Regards!

Looks like this API works for the "Xen VNC proxy" service only. The
console manager triggers the console creation here:
https://github.com/openstack/nova/blob/66c661258873e2544e286099c4bc027c26c851c4/nova/console/manager.py#L79


The XVPConsoleProxy implements it here:
https://github.com/openstack/nova/blob/46b3a3ca1ac3a5ffdc7c5420263223f2d3b9a660/nova/console/xvp.py#L56-L58


Looks like that service runs with default Devstack settings as service
"nova-xvpvncproxy":
https://github.com/openstack-dev/devstack/blob/f3b2f4c85307b14f115a020f5eaf6c92026b55b4/lib/nova#L892-L892


The API microversion 2.6 introduced a consolidation of the remote consoles:
https://github.com/openstack/nova/blob/3e032fd45be28c6098235ce336e675d03ebc6619/nova/api/openstack/compute/schemas/remote_consoles.py#L101-L102


Could it be that the "GET /console" API shouldn't be available anymore
since microversion 2.6?
