Re: [PATCH v2] conf: Report alias name of the detached device in error

This is v2 from: https://listman.redhat.com/archives/libvir-list/2021-May/msg00481.html I have reworked the code a bit to have only one error report instead of multiple ones with different combinations of possible matching items.
