[libvirt PATCH 10/10] conf: stop ignoring <loader>/<nvram> with firmware auto-select
Daniel P. Berrangé

Tue Feb 15 18:54:38 UTC 2022
Currently if the <os> firmware attribute is set then we silently
ignore most of the <loader> and <nvram> element configs. This
changes the code so that we always fully parse the <loader> and
<nvram> but then use a post-parse method to explicitly reject
invalid combinations.
