Supporting development mode for no confidential hardware environments?

[jinbpark]

Hi, I have a question as to whether SVSM, in the current form, is supporting a kind of simulation mode for no confidential hardware . (e.g., confidential container offers an option to explore its features without confidential hardware- blog article)

It might be allowing other engineers to explore and try out SVSM, without SEV-SNP hardware. As SVSM currently relies on VMPLs for isolation, such (simulation) feature would require developing SW-based isolation that mimics VMPLs but provides no security guarantees.

After a few research, it seems that SVSM doesn't have such a feature. Am I correct? If so, do you have a plan to develop it?
