Hey,

and this means, that it is a bug in Nova Compute.
Trying to follow your hint, to (fake) terminate, to reset the state, did
not work,
as it is now also in infinite Termination state.

Am I too rude to my install, or is it that Nova is not really as production
ready as the internet showed me.

Best regards,
Christian.
