What I tried now:
run your 3 steps with qubesctl top.enable qvm-sys-gui-gpu
qubesctl top.enable qvm-sys-gui-gpu pillar=True
qubestctl --all state.highstate
And the last step I just got one error with code 1 for sys-firewall, but think that shouldn’t be the problem and my system is working and didn’t crashed;) Now I have got 1 sys-gui-gpu as a Vm in the qubes-manager. But they didn’t boot automatically at system start and I need to run it first.
I don’t know why that vm is based on my fedora-33-xfce template ,because I don’t have selected this one as my main in the global settings, but if that bringst not some problems then it is wayne weather vm the gui-gpu is running. How do u mean to attach the nvidia cards to the vm? Just in the Qubes-Manager under Devices and add the pci /pcie of my two nvidia 980m cards to it or I need to do it other way?
thank you again for ur great help
edit: starting the vm first works but immeditately shutdown again with the error no such file or directory /usr/bin/qubes-input-trigger-dom0 --all --dom0 failed with erno2 -is that because I haven’t attached the nvidia cards to the vm now?
Before using the 2nd way I disabled the sys-gui-gpu running qubesctl top.disable qvm.sys-gui and then started with
2nd method enable sys-gui not sys-gui-gpu . That is working after rebooting the system the vm starts in a green state and just was a error 20 at the last step running qubesctl --all state.highstate sys-gui but that shouldn’t be a real error and be problem. But I have to read the documentation again and much more detailed, because now I don’t know if already my vm’s have gpu passthrough or I need to add my video cards or sth like that first;)
And this vm is based on my fedora-33-xfce template,too but I don’t select it, but like I said if that is working then the template is wayne for me.
Of course if anyone is trying it,too u need to run all these commands with sudo or u will get permission denied;) And I am not logged of from my system;) Maybe that new is still experimental and not highly experimental and don’t be too afraid to try it
