EFI shell access from OVMF boot menu

Hi, I am trying to get into UEFI shell booting an empty vm with an atatched ISO. I explored OVMF Boot Maintenance Manager but I cannot find the standard UEFI shell option. Could it be the efi shell binary is not present by default when using incus ? This is a neophyte question so sorry if I missed something obvious…

It depends on the UEFI firmware build.

Because of the UEFI shell being a signed binary, it could be used to attack a secureboot environment. For that reason, the stable Zabbly packages as well as packages from quite a few distributions do not include it anymore.

We still include it in the daily builds for the Zabbly repository though.

It may be possible to manually build the uefi shell and attach it as a cdrom drive or similar, though you’ll need to turn off secureboot then.
