And finally the last missing piece. This is what puts it all
together.
At the beginning, qemuFirmwareFillDomain() loads all possible
firmware description files based on algorithm described earlier.
Then it tries to find description which matches given domain.
The criteria are:
- firmware is the right type (e.g. it's bios when bios was
requested in domain XML)
- firmware is suitable for guest architecture/machine type
- firmware allows desired guest features to stay enabled (e.g.
if s3/s4 is enabled for guest then firmware has to support
it too)
Once the desired description has been found it is then used to
set various bits of virDomainDef so that proper qemu cmd line is
constructed as demanded by the description file. For instance,
secure boot enabled firmware might request SMM -> it will be
enabled if needed.
