I do not understand what you mean by “primary surface conditions”?
Do you mean the state of the primary surface, or specific conditions
testing the primary surface, or something else?

While you are at it, why not make allow_now a bool?

I would rephrase this comment to be closer to your commit message log,
i.e. that with 3D enabled, qemu does not create a QXL primary surface.

Any reason to not set use_hardware_cursor in the 3D case?
Actually, looking at the rest of the code, I did not understand why we have a field for that.
