Hey,
I'll paste the interesting part of domain XML here so that it doesn't
get lost:
hvm
/usr/share/edk2-ovmf/OVMF_CODE.fd
/var/lib/libvirt/qemu/nvram/vm1_VARS.fd
And then in qemu.conf you define the pair:
nvram = [
"/usr/share/edk2-ovmf/OVMF_CODE.fd:/usr/share/edk2-ovmf/OVMF_VARS.fd",
"/usr/share/edk2-ovmf/OVMF_CODE.secboot.fd:/usr/share/edk2-ovmf/OVMF_VARS.secboot.fd"
]
But as the comment in qemu.conf (just above your line) says, this is
ignored if FW metadata files exist which is exactly your case and this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1763477
For your convenience you can switch to (the
element will be removed automatically) or if you insist on
using the old style then provide @template attribute to :
/var/lib/libvirt/qemu/nvram/vm1_VARS.fd
There is an internal list that is still consulted when finding matching
_VARS fails, but your path is not on it:
https://gitlab.com/libvirt/libvirt/-/blob/master/src/qemu/qemu_conf.c#L98
But it exists mostly to give distros enough time to switch to FW
descriptors.

thanks for the detailed explanation, I wanted to be sure I understand. the
following is needed to be done:
1. replace this:
hvm
/usr/share/edk2-ovmf/OVMF_CODE.fd
/var/lib/libvirt/qemu/nvram/vm1_VARS.fd
to this:
hvm
Here, nvram will be generated, but if you want some other path than
libvirt would generate you can provide it under . Yes. But
you're using the default path anyway.
2. patch qemu_conf.c to include the custom paths of my fd files?
There is a third option. Save the following under
/etc/qemu/firmware/50-my-ovmf.json:
{
"description": "UEFI firmware for x86_64",
"interface-types": [
"uefi"
],
"mapping": {
"device": "flash",
"executable": {
"filename": "/usr/share/edk2-ovmf/OVMF_CODE.fd",
"format": "raw"
},
"nvram-template": {
"filename": "/usr/share/edk2-ovmf/OVMF_VARS.fd",
"format": "raw"
}
},
"targets": [
{
"architecture": "x86_64",
"machines": [
