[Starlingx-discuss] Couple of questions about STX

thanks for the answer. Starting with OpenStack VMs. Containers via K8S might also be a later possibility.
So everything running on OpenStack will work with STX? I know that windows works with OpenStack.
The kvm in STX supports RT by VMs?
Is there any information about the demos you were talking about. Would be interested in gained experiences there.
