Subject: [PATCH] qemu: Match NVRAM template extension for new domains
Keep things consistent by using the same file extension for the
generated NVRAM path as the NVRAM template.
Signed-off-by: Andrea Bolognani <abologna@redhat.com>
Reviewed-by: Michal Privoznik <mprivozn@redhat.com>
(cherry picked from commit b845e376a45a8e93f933a4a41068a9ce27adf755)
