I reproduced this using:

$ kvm -bios /usr/share/OVMF/OVMF_CODE.fd -device e1000,netdev=n1 -netdev user,id=n1,tftp=/boot/efi,bootfile=/EFI/ubuntu/grubx64.efi

and manually booting shim from the iPXE commandline which then tries to chainload grubx64.efi.

iPXE> boot tftp://10.0.2.2/EFI/boot/bootx64.efi
tftp://10.0.2.2/EFI/boot/bootx64.efi... ok
