[SOLUTION] So I re-created the VM from scratch using those machine config values below right away, and it seems to have worked! Whereas the error below occured because I originally created the Windows VM as usual (using seaBios, KVM CPU etc...) and then I tried changing those to the values below. So the solution perhaps is to create the VM from scratch properly the first time, instead of trying to change it later.

Hello,

My Windows 10 VM fails to start. I'm following GPU pass through guides (Reddit, Youtube).

The error I see is exactly the same as this post but their solution of just 'disabling secure boot' still doesn't work for me.

<Pressing 'Esc' repeatedly to enter some TTY, then typing 'esc' to enter the BIOS of the VM>
