in July 2021, VMWare has officially discontinued the rbvmomi gem. (Update README.md · vmware-archive/rbvmomi@fb3caa9 · GitHub)
From what I understand by looking at VMWare related isues (like Bug #27670: Update rbvmomi to support new VMware hardware versions and guest OSes - Packaging - Foreman and Bug #34498: CentOS9 and RHEL9 Guest OS are missing - Foreman), this means we cannot get access to new GuestOS definitions and VMWare hardware versions.
The Windows team at my company has been complaining for a while that we cannot deploy VMs with current Windows releases set as GuestOS by default, and from the issues I linked it looks like this will be the case for RHEL9 too and also new HW Versions in future VSphere releases.
Are there any plans for replacing that gem or forking it or something similar? If not, what would be the other options?
