Would be most efficient. That way you can allocate the proper resources to each

You don't run VMs for efficiency, because they are not efficient. You run VMs if you need to isolate an app/OS, or if you need the ability to move VMs around to different hardware easily.

VMs are inefficient because not only are you adding the overhead of a hypervisor, but you are also presumably running multiple full OSes. On top of that, if you don't allocate precisely the resources a particular VM needs, then the extra resources are wasted as any other VMs can't use them.

You get most of the advantages of VMs by using containers instead, like Docker. A container holds an app and all of its supporting files, so it can be moved around to different machines. They also run in isolated environments (though not as isolated as a VM). They use system resources much more efficiently since they share the host OS rather than running their own OS. This also means they spin up much faster since they don't have to boot a full OS. Also you can limit the resources available to a container, though you don't have to (in which case they will use what the host OS has available). I guess the only real downside is you can't run multiple OSes, so running something like Blue Iris on a Linux Docker host might be tricky ( though apparently that sorta works using WINE).
