I’m facing a similar problem to this one, but I’m unable to find any solution via google.


I’m trying to run an EFI BIOS using qemu.

  * It works fine without acceleration
  * It hangs (display not initialized) when using -accel hvf

I’ve tested many OVMF.fd files from internet including the official one of course whith no differences. (always work with no acceleration and always fail with HVF acceleration).

  * OS: MacOS 10.14.6
  * QEMU 5.0.0 monitor - type 'help' for more information
  * (qemu) qemu-system-x86_64: warning: host doesn't support requested
    feature: CPUID.80000001H:ECX.svm [bit 2]
  * info roms
  * fw=genroms/kvmvapic.bin size=0x002400 name="kvmvapic.bin"
  * addr=00000000fff00000 size=0x100000 mem=rom
  * /rom@etc/acpi/tables size=0x200000 name="etc/acpi/tables"
  * /rom@etc/table-loader size=0x001000 name="etc/table-loader"
  * /rom@etc/acpi/rsdp size=0x000014 name="etc/acpi/rsdp"

Is it a known issue?

Is there something I’m missing?

I’m running qemu in the following way:

qemu-system-x86_64 -machine q35 -bios ~/data/OVMF.fd -monitor stdio

If I add -accel hvf, it’ll hang before tiano core logo.

Best regards,
