No problem. I just thought I had covered that when I said:

That’s some incredible stuff. Now days you can use things like XCP-ng to do the same but VMware was ahead of the pack for a decade.

They started dying when they were squeezed between cloud hyper scalars and the cheaper alternative hypervisors that finally had caught up.

This being said I don’t think even in 2025 proxmox and things like vsphere are comparable. XCP-ng I do think is though. It’s open source and matches features.
