QEMU for some other things. I think QEMU provides better hardware
emulation - for example, VirtualBox doesn't emulate the PC speaker,
while QEMU does.
Hyper-V is Micro$oft's internal/"native" hypervisor/virtual machine, 
that comes in a number of higher end Windows 10+/Windows Server versions 
by default (at least in a limited #of concurrent guests version).


It is just like a lot of Microsoft products very "MIcrosoft centric", so 
compatibility with something older like DOS might be limited. I 
personally just have never bother to play with it for all those years...

I don’t use Hyper-V. But, I can tell you a couple general things to consider.

Modern UEFI only systems and DOS don’t play well together at all. VirtualBox 
will let you run DOS on such systems under a host OS.

There very few programs under DOS that can talk to most on-board audio in 
modern machines. VirtualBox will provide a sound card emulation layer that can 
be used by many programs and games.

Under VirtualBox you will need to live without sound for programs that use the 
PC speaker for audio under DOS. 

VirtualBox does not fully emulate all the features of VGA. While generally that 
isn’t a problem. Some programs and games may not be able to work as designed or 
at all. 

Some games and programs just don’t work under VirtualBox or most other 
Emulators for unknown reasons. 

The basic networking support provided with FreeDOS works fine under VirtualBox. 
However, there are only a handful of programs that will be helpful in doing any 
kind of remote drive mapping. So, getting files in and out of the VM requires a 
little more effort.

You may consider one of the DOSBox variants instead. 

Basic networking is not supported. However, you can install FreeDOS in a hybrid 
mode (default under DOSBox). That install mode installs FreeCOM and all the 
other bells and whistles. However, it does not install the FreeDOS kernel. 
Instead it uses the DOSBox kernel. This allows direct access in the DOSBox to 
specific folders on the Host as if they were DOS drives. 

DOSBox has pretty good emulation for sound card support under DOS.
DOSBox emulates many of those obscure VGA features not provided under 
VirtualBox.
DOSBox emulates the PC speaker.
DOSBox can be sped up or slowed down for older games that have problems on fast 
machines.
Of those occasional programs and games that just don’t work in VirtualBox, most 
work fine under DOSBox. Although, there are a couple that only seem to work on 
real hardware.

Equally newb reply... It's there any advantage over installing virtualbox
and running freedos there?

Probably yes. Just don't use UEFI. Why didn't you try first?

Your question is rather ambiguous. If you are asking if you can run 
FreeDOS in a guest OS in a Hyper-V host, then the answer is likely a 
"maybe", at least it should work if any other DOS works as  Hyper-V 
guest. (I have successfully stayed away from Hyper-V, at least as far as 
I could throw the computer running it)
