Am I to understand that GRUB (and its config) are correctly loaded via iSCSI? > 6.

I never tested it, but I guess it should work (for some value of "work"). Since I never tested it, I can't say what code in OvmfPkg would require specific support (perhaps the boot order library... dunno). > 2. Can I help in further analyzing the issue? It could be an issue in EDKII > (drivers?), in grub or in the Linux kernel. Your email is missing almost all of the important details, so let's start again. :) - Are you using libvirt? If so, what version? What is your domain XML? - What version of QEMU are you using? What is your command line? - How did you build OVMF? Do you have a verbose debug log from the OVMF run? - I could probably derive the answer to the next question from the above, but I'll ask anyway: are you using iPXE (bundled with QEMU) for driving your virtual NIC (utilized by edk2 and grub), or OVMF's builtin virtio-net driver? If you don't know (or use a NIC model different from virtio-net), then the answer is iPXE. - What is the complete (= "ignore_loglevel") guest kernel log, up to and including the crash?
