[vfio-users] OVMF: Boots only first time after driver installation

[S B]

The file hw/misc/vfio.c does not exist anymore. I only found DEBUG_VFIO in
include/hw/vfio/vfio-common.h.
I compiled the via makepkg and included the patch below, but the output
does not change.
I checked the line while compiling and it is changed. I compiled it twice
and installed it, but the output does not change.
Maybe it did sth wrong but I do not find my mistake. Any hints?
