Understood; however, how do you propose to accomplish that in
domain_conf code that's supposed to be hypervisor agnostic?
It's not like we can pass around a qemuCaps so that when
virDomainDefMaybeAddController can call the get default model function.
This ended up being the least offensive way I could determine would
accomplish the task even though it.
The other thought I had was jiggling the order of the call to
virDomainDefPostParseCommon to before the iteration of the devices
(virDomainDeviceInfoIterateInternal), but doing that scared me more than
taking the option to follow how serials and videos handled similar
adjustments after post parse was called.
In any case, thanks for the speedy review. I'll push what's here and
maybe someone else will propose some other brilliant suggestion.
Tks -
