Based on information provided in comment #1 I see that each host is different in RHV. uid_ems is unique and I see that there were 3 hosts where 2 of them used the same guid (possibly host reuse). I am not able to access customer case due to timeout. Please provide more information about the issue and the steps to reproduce.
As I mentioned in comment #4 based on provided information it looks like not a bug. Please provide the evm and rhevm logs.
Sandro, Is it possible that a host name is changed during engine upgrade?
Adding back needinfo
(In reply to Piotr Kliczewski from comment #9) > Sandro, Is it possible that a host name is changed during engine upgrade? No. For renaming the engine host there's a separate tool which doesn't perform upgrades. If you want to change name and upgrade, you need to do it in 2 steps. See https://ovirt.org/documentation/admin-guide/chap-Utilities/#the-ovirt-engine-rename-tool

That's correct in 5.9 we removed the unique hostname requirement for all providers. > Adam, hoe risky is the backport of your patch which removes host name suffixes > to 5.8.z? It isn't risky and it should cherry-pick cleanly, https://github.com/ManageIQ/manageiq/pull/15795 for reference

Verified on CFME-5.8.4.2/RHV-4.2.2.5 Added 2 RHV providers with hosts, that have same names. The hosts were added with the same name. There was no use in any suffix number, as was before, on CFME-5.8.3.
