Booting UEFI
To boot UEFI systems using QEMU, the UEFI firmware replacing the BIOS implementation needs to be provided while starting QEMU.
The following installs a script, that always starts QEMU with OVMF firmware implementing UEFI support.
environment = {
(pkgs.writeShellScriptBin "qemu-system-x86_64-uefi" ''
qemu-system-x86_64 \
-bios ${pkgs.OVMF.fd}/FV/OVMF.fd \
"$@"
'')
};
qcow-efi images generated from nixos-generators require more RAM than the default 128MB. Failing to provide enough RAM results in grub reporting "error: start_image() returned 0x800000000000009." or systemd-boot reporting "Failed to execute NixOS: Out of resources".
