Check your xml, there should be lines like this:
<os>
<type arch='x86_64' machine='pc-q35-2.7'>hvm</type>
<loader readonly='yes'
type='pflash'>/UEFI_OVMF/OVMF_CODE.fd</loader>
<nvram>/home/username/.config/libvirt/qemu/nvram/vm_VARS.fd</nvram>
... or in /var/lib/libvirt/qemu/nvram, if you're using
the system-wide libvirtd instance.
Anyway, Aleksei is right that you should copy over the
variable store (vm_VARS.fd) along with the disk image
and the XML configuration: some guest operating systems
are able to cope with its absence and recreate the
correct EFI variables automatically, but that's not
always the case.
Moreover, you should make sure your /etc/libvirt/qemu.conf
file contains something along the lines of
nvram = [
"/usr/share/edk2.git/ovmf-x64/OVMF_CODE-pure-efi.fd:/usr/share/edk2.git/ovmf-x64/OVMF_CODE-pure-efi.fd/OVMF_VARS-pure-efi.fd"
]
so that, in case the variable store for the guest is missing
or your simply creating a new guest, libvirt will be able to
create a new one by copying over the template (the "master
var store" the error was referring to).
By the way, edk2-ovmf is included in Fedora proper these
days, you don't need to use edk2.git-ovmf-x64 any longer ;)
