Hi, could you please add it also here:
https://tmt.readthedocs.io/en/stable/spec/plans.html#virtual

to make it easy to discover. To me it is not obvious that hardware is something usable for virtual provider.

Is it necessary? The provision section states that this method works for all of them, to some degree depending on what each plugin can deliver: https://tmt.readthedocs.io/en/stable/spec/plans.html#provision

As part of the provision step it is also possible to specify detailed hardware requirements for the testing environment. See the Hardware specification section for details.

Maybe it's just me, but when I'm looking for something in the documentation I'm not reading it from start of the section but looking on the details of the given specific part. But I'm fine even with this solution.

In general, this is not the first time I failed on using TMT documentation to find stuff. For some reason the documentation is confusing to me. I'm more used to podman like kind of documentation where each of the commands (leaf part) has a complete information to what can be used there.
