How to make virtual machines without a network, but with remote control?

Question

Computer networks

Hello. Please tell me what are the options for virtual machines or their bundles with something in order to achieve the effect of several virtual machines with windows, inside which there is no network at all. But remote access to these VMs should be.
End result: a "server" running windows, with windows virtual machines on board. On the "server" the Internet is. But in virtual machines, the network card is simply missing. But these virtual machines need to be managed by remote users over the Internet.
So the question is - how and with what software can this be done?

Answer 1

If you need remote access to the virtual console of virtual machines, then any hypervisor can do this. Either through your web console (ESXi 6.0 and up, ProxMox), or using your management software (ESXi 6.0 and up, XenServer), or directly provide console access via RDP or VNC (VirtualBox, KVM). Also, the corresponding functionality is in the client control panels used by virtual server hosting.

Answer 2

On qemu+kvm this can be done. You can use the ready-made proxmox distribution .
There is always vnc access to the graphical interface of each virtual machine, while the network adapter can be removed from the configs altogether.
As a result, you will get a bunch of vnc ports to access each virtual machine, but none of them will have a network interface, and, therefore, the Internet.

Answer 3

Any hyper is able to give the "virtutal console" of the machine. The ability to work with it will, of course, be only through this very console, which is not very convenient, but there may not be a network network there - the main thing is that the VM management environment should be accessed.
