the acceleration preference which defaults add option '-accel hvf' in the front of '-accel tcg,tb-size=2560' to use native hypervisor framework. but it causes issue EFI stub: ERROR: This 64 KB granular kernel is not supported by your CPU
I have multi guest OS, the most can normally boot into system powered by the native hypervisor but only one.
so if i want the only one can normally boot i must only check the global disable acceleration preference.

I think '-accel hvf' can be put into guest instance preferences and make it effective default.
I agree! Duplicate of #2493
