Add support for mac spoofing and dynamic memory.
To enable nested virtualization, mac spoofing, no dynamic memory and at least 4gb of ram should be set for the vm. Set warning if this has not been done. Detected Virtualization Extensions are supported by the machine your are running on, as it only works for Windows 10 and Windows Server 2016 onwards.
