Looks like that commit also "lost" the compatible device check on detach
too (e.g. ACTION_DETACH) without explanation. Whether at the time it
then became the last consumer of virDomainDeviceAction is another question.
So, since you're bringing this back to life - should those checks be
reinstated into the Detach code (lxc, qemu)? If not, surely
ACTION_DETACH then still isn't used.
Can I assume you tested bz1439991 with the new condition?
The restoration of what's been done thus far looks fine, just need some
more details...
