The fix consisted of having a check tailored exactly for +this use case and if it's hit then using FW autoselection to +figure it out. Unfortunately, the NVRAM template is not saved in +the inactive XML (well, the domain might be transient anyway). +Then, as a part of that check we see whether the per-domain copy +doesn't exist already and if it does then no template is looked +up hence no template will appear in the live XML. + +This works, until the domain is migrated. At the destination, the +per-domain copy will not exist so we need to know the template to +create the per-domain copy from. But we don't even get to the +check because we are not starting a fresh new domain and thus the +qemuFirmwareFillDomain() function quits early. + +The solution is to switch order of these two checks.
