The following command ends in minimal GRUB shell: sudo qemu-system-x86_64 --enable-kvm -bios ~/edk2/Build/OvmfX64/DEBUG_GCC46/FV/OVMF.fd -m 1G -cdrom /srv/iso/install-amd64-minimal-20180830T214502Z.iso Works fine with qemu bios. I've tried several OVMF versions, including latest one, all failed. Related bug: https://bugzilla.tianocore.org/show_bug.cgi?id=1141
This seems to be a GRUB issue. On our catalyst grub config we're using "search --no-floppy --set=root --file livecd" to locate the cdrom root and load a real config from there. In my initial testing, grub's "search" command doesn't seem to work at all when booting QEMU/OVMF. On real hardware (or other working VMs), I can drop to the grub> shell and "search --no-floppy --file /livecd" returns "cd0" On QEMU/OVMF, it returns "error: no such device: /livecd." But if I do "ls (cd0)/", the livecd file is found, so the device is there and visible. I cannot get any "search --file=foo" command to work on QEMU/OVMF.
For some reason it seems that the --no-floppy option is causing this. You can get this to boot if you manually enter: grub> search --set=root --file /livecd grub> configfile /grub/grub.cfg
Created attachment 545844 [details] screenshot of grub behavior Here's the gist of the problem in one screenshot
I used OVMF_CODE.secboot.fd from Fedora's edk2-ovmf-20190308stable-1.fc31.noarch.rpm to boot install-amd64-minimal-20190313T214502Z.iso. With this setup, Grub correctly loads it's configuration. Using the same ISO and Gentoo's OVMF_CODE.fd from sys-firmware/edk2-ovmf-2017_p20180211 Grub fails as described above. So, its probably the newer version of the OVMF firmware that fixes the issue.
Good find. I can confirm that edk2-ovmf-9999 from upstream git works fine as well.
