I'm using Apple's Virtualization.framework, not QEMU.
It doesn't use UEFI when it directly loads bzImage. ( dmesg: https://bugzilla.kernel.org/attachment.cgi?id=304323 )
Despite that, it still expects LINUX_EFISTUB_MINOR_VERSION (include/linux/pe.h) referred from arch/x86/boot/header.S to be 0x0. I confirmed that the kernel can boot by just setting LINUX_EFISTUB_MINOR_VERSION to 0x0.
Would it be possible to revert the LINUX_EFISTUB_MINOR_VERSION value (not the actual code) to 0x0? Or will it break something else?
Anyway, I'll try to make a request to Apple to remove the LINUX_EFISTUB_MINOR_VERSION check.

Which versions of qemu and OVMF are you using?
