Yes, you can use skypilot On-Prem to work with a VM acquired from a cloud not supported by skypilot. However, the current On-Prem support has been deprecated and is no longer supported. Instead, it is recommended to use the new and experimental Kubernetes support. This will allow you to run SkyPilot tasks on a Kubernetes cluster. To try it out, you will need to deploy a Kubernetes cluster on your VM and follow the provided steps. Note that this feature is under active development and some functionalities may not be supported yet.
