Hi guys.
I've have a guest and that guest differs from all other guest by:
<os> <type arch='x86_64' machine='pc-q35-rhel9.0.0'>hvm</type> <loader readonly='yes' secure='yes' type='pflash'>/usr/share/edk2/ovmf/OVMF_CODE.secboot.fd</loader> <nvram>/var/lib/libvirt/qemu/nvram/ubusrv1_VARS.fd</nvram> <boot dev='hd'/> <bootmenu enable='yes'/> </os>
whereas everything else has:
<os> <type arch='x86_64' machine='pc-q35-rhel9.0.0'>hvm</type> <boot dev='hd'/> <boot dev='cdrom'/> <bootmenu enable='yes'/> </os>
Now, that different guest fails - as the only one - to start, to boot after its qcow2 image was luks-encrypted. Guest starts but says that:
BdsDxe: failed to load Boot0001 "Uefi Misc Device" from PciRoot (0x0)/Pci(0x2,0x3)/Pci(0x0,0x0): Not found
revert back to original, non-encrypted qcow2 image and all works a ok. Please attach either the full XML or at least the disk part for *both*

When I add encryption to <disk> & use encrypted qcow2 then VM fails as I described. I specifically asked for '*both*' XMLs. The working one. And the non-working one.
In case it might not be clear - which in my mind should not have been as it's simple, sure only in my mind - it is: all guests use almost identical "template" with obvious differences, such as names/paths, hw adresses, now... - tree guests have used 'pflash' in <os> from the beginning, always. and I point to that as only those three guest fail to boot after their qcow2s were encrypted, just like all other VM's were, but those other VM's start & boot okey. If in those three VMs I use original, non-encrypted qcow2 - without changing anything else in XML definition but 'encryption' relevant in <disk> - then those VMs start & boot just fine. thanks, L.
