Public bug reported:

Description:
===

Currently, setting hw_firwmare_type=uefi on Ubuntu 20.04
might create _unbootable_ servers on Ussuri and Victoria
(Wallaby and later are OK).

Steps to Reproduce:
===

$ openstack image set --property hw_firmware_type=uefi $IMAGE
$ openstack server create --image $IMAGE --flavor $FLAVOR --network $NETWORK uefi-server

Expected Result:
===

The server's libvirt XML uses UEFI _without_ Secure Boot.

        <loader readonly='yes'
type='pflash'>/usr/share/OVMF/OVMF_CODE.fd</loader>

Guest boots, and console log confirms UEFI mode:

        $ openstack console log show srv | grep -i -e efi -e bios
        ...
        Creating boot entry "Boot0003" with label "ubuntu" for file "\EFI\ubuntu\shimx64.efi"
        ...
        [    0.000000] efi: EFI v2.70 by EDK II
        [    0.000000] efi:  SMBIOS=0x7fbcd000  ACPI=0x7fbfa000  ACPI
        2.0=0x7fbfa014  MEMATTR=0x7eb30018
        [    0.000000] SMBIOS 2.8 present.
        [    0.000000] DMI: OpenStack Foundation OpenStack Nova, BIOS 0.0.0 02/06/2015
        ...

Actual Result:
===

The server's libvirt XML uses UEFI _with_ Secure Boot.

        <loader readonly='yes'
type='pflash'>/usr/share/OVMF/OVMF_CODE.secboot.fd</loader>

Guest doesn't boot; empty console log; qemu-kvm looping at 100% CPU.

        $ openstack console log show srv | grep -i -e efi -e bios
        $ openstack console log show srv | wc -l
        0

        $ juju run --app nova-compute 'top -b -d1 -n5 | grep qemu'

          67205 libvirt+  ... 100.0   1.4   1:22.38 qemu-sy+

Environment:
===

- Hypervisor running Ubuntu 20.04 LTS (Focal)
- Nova from Ussuri (Ubuntu Archive) or Victoria (Cloud Archive).
