Package: gnome-boxes
Version: 45.0-1
Severity: normal

Dear Maintainer,
If I attempt to create a GNOME OS guest I end up on the edkII console.
If inhte console I try to boot the EFI (in FS0: be it bootx64.efi in
\EFI\BOOT or systemd-bootx64.efi in EFI\systemd) I get a "Command Error
Status: Access Denied" error.

I got he clue it might be secure boot related by 
https://forum.proxmox.com/threads/vm-always-going-into-uefi-interactive-shell.119215/

I also learned that the install was fine with the flatpak, so I compared
the VM configurations for GNOME OS:

Debian gome-boxes 45:
  <os firmware="efi">
    <type arch="x86_64" machine="pc-q35-8.0">hvm</type>
    <firmware>
      <feature enabled="yes" name="enrolled-keys"/>
      <feature enabled="yes" name="secure-boot"/>
    </firmware>
    <loader readonly="yes" secure="yes" 
type="pflash">/usr/share/OVMF/OVMF_CODE_4M.ms.fd</loader>
    <nvram 
template="/usr/share/OVMF/OVMF_VARS_4M.ms.fd">/home/prahal/.config/libvirt/qemu/nvram/gnomenightly_VARS.fd</nvram>
    <boot dev="cdrom"/>
    <boot dev="hd"/>
    <bootmenu enable="yes"/>
  </os>
  <features>
    <acpi/>                 
    <apic/>
    <smm state="on"/>                     
  </features> >

Flatpak gnome-boxes 44:
  <os firmware="efi">
    <type arch="x86_64" machine="pc-q35-7.2">hvm</type>
    <boot dev="cdrom"/>
    <boot dev="hd"/>
    <bootmenu enable="yes"/>
  </os>
  <features>
    <acpi/>
    <apic/>
  </features>


Grepping where this secure-boot feature comes from, I ended up on:
/usr/share/qemu/firmware/40-edk2-x86_64-secure-enrolled.json

Scrambling the target (for example, replacing in "machines", "pc-q35-*"
by "pc-q35xxx-*") in this file to avoid its settings being added to
(all?) the  guest VM I now can install "GNOME OS Nightly x86_64" (ie
edk2 boots into the installer and the installer proceeds).

This might well be an ovmf bug.
Still, as I don' know if gnome-boxes or qemu have flags to avoid ovmf
bringing in this secure-boot for all guest setups, I start up the stack.


Cheers,
Alban
