Comment 1 for bug 1709260

For clarity on the bug report, could you please provide the nova-sceduler log that shows the filter missing that host because the name is different ?

TBC, all FQDNs are case-sensitive, so we should probably indeed return a 404 when you're trying to add a host with the wrong case. The only point I wonder is whether it would require a new API microversion since we were previously accepting that from a REST perpective (my guts tend to say yes to that :( )
