@mspencerl87 You need a dummy plug or some sort of virtual monitor like usbmmidd

@splastunov By 7.3.0 i meant the package version and that version was also in xcp-ng 7.4 so if the package was there and its license hasn't changed since i would assume it means its still free to use.

@splastunov Thats where i found about the package and from what i've found the license in the open source version 7.3.0 and the current closed source 7.4.8 are literally identical which probably means the closed source one is free to be used without any licensing from Citrix.

I tried using the 7.4 package on 8.2 xcp but for some reason it doesn't work, when i tried to install it it gave me the following errors:

libxenctrl.so.4.7()(64bit) is needed by vgpu-7.3.0-1.x86_64
       vgpu < 7.3.3 is obsoleted by (installed) xcp-ng-deps-8.2.0-12.noarch

Which is weird because the libxenctrl.so. is actually a higher version on 8.2 so why would it need the older one and i have no idea what it means by "7.3.3 is obsoleted by (installed) xcp-ng-deps-8.2.0-12.noarch"

The vgpu emulator/rpm thats needed to use Nvidia's vgpu software became closed source after 7.4 but you can still get it from the xenserver ISOs and i would like to know if its non closed source versions are free to use, the license https://pastebin.com/PAXvP2rT seems to point in the direction that it's free to be used but i would like to get more clarification.
