See ConditionVirtualization directive in man systemd.unit. Yes. After knowing what it was called I found it. I blame my 67 years old eyes and feeling bad after Moderna shot. I have tested it in my use case and that is exactly what I needed.

[systemd-devel] Bare Metal or VM
Hi, This may be an "uninformed" question since I've not done much with systemd. Is there a way for a service or unit to be aware if the environment is Bare Metal or a Virtual Machine. For example, a unit is triggered by a user logging in as a graphical user. But, I only want the unit's ExecStart to be processed if the environment is a qemu VM. I'd rather not have the process started on Bare Metal since it would be unused.
