windows Server Running on the Hyper V

we have virtual server on one physical machine . victual machine is running   company application and member of domain  . physical server OS on top of few other application running  . but physical server is not member of domain  . I hope right setup is both the servers should  be member of domain and keep the physical server OS without installing any application ?

please comment on the best practice on the setup . fi you can please let me know the industry standard to have the memory and the hard disk space physical to virtual server  . Only one victual machine in this  setup    

Is it OK to run the AD in the virtual machine ?

Yes you can run Ad on VM.

I will do 1 machine with aplication and 1 machine with DC and AD.

I have an EE article that should help: Some Hyper-V Hardware and Software Best Practices.

Yes, AD is fine as a VM on the host.
