Side comment: OVMF supports virtio-fs, and using virtio-fs could speed up your develop/build/test cycle. Assuming your UEFI application does not crash or hang (i.e., assuming it exits cleanly and you can continue using the same UEFI shell session), virtio-fs could be a small productivity boost for you, as you wouldn't have to re-launch QEMU every time. The idea is to build your application through some platform DSC file as follows -- note that it need not be an OVMF DSC file, but it may be one, if you prefer that: build -a X64 -b NOOPT -p MyAppPkg/MyApp.dsc -t GCC5 \ -m MyAppPkg/MyApp/MyApp.inf You don't need an FDF file for this, just grab the resultant "MyApp.efi" binary from the Build directory. Then copy "MyApp.efi" (on the host side) under the virtio-fs root directory somewhere. When the copy operation completes (on the host side), just switch your focus to the guest UEFI shell window, and you can immediately execute the just-built application. I find using virtio-fs by far the easiest with libvirt, but you can use it from the bare QEMU command line, too. https://libvirt.org/kbase/virtiofs.html https://virtio-fs.gitlab.io/howto-qemu.html This assumes that your development environment is Linux-based, as the virtio-fs daemon (which runs in tandem with QEMU on the host) is Linux-only.
