bare metal server, minimal installation
This suggests a server with console mode only. Have you installed the necessary packages for GUI ( Xorg ) on this server?

I guess it is not.
Two questions:
1. Do I need GUI tool if I am planning to run VB using CLI? I have installed vagrant afterwards. Vagrant was able to install boxes without any issue.
2. If I install a windows box ( for example Win 2000 Server ). Will I be able to connect to it using remote desktop without having any GUI tool installed in the host machine.

1) Don't know. I don't use vagrant and it is not supported here.
2) Same answer as above.
I can say if the host does not support some features the guest will not have them available, IE: 3D Accel., Etc.
