[PATCH 2/9] conf: Move virDomainGenerateMachineName to hypervisor/
Michal Privoznik
mprivozn at redhat.com
Wed Mar 25 10:18:02 UTC 2020
The virDomainGenerateMachineName() function doesn't belong in
src/conf/ really, because it has nothing to do with domain XML
parsing. It landed there because of lack of better place in the
past. But now that we have src/hypervisor/ the function should
live there. At the same time, the function name is changed to
match new location.
