I’m the first to admit that I read the documentation for Calm a bit too quickly and didn’t really reflect on the meaning of “The Prism Central in which Nutanix Calm is running is registered with the same cluster.” and “Nutanix Calm is supported only on AHV and ESXi hypervisors on a Nutanix cluster.”
After trying and failing to run this on an existing VMware cluster, that the Prism Central/Calm installation doesn’t own, I re-read the documentation and realized that I’d glossed over the actual requirements.
I mention this to clarify that this isn’t a post about unclear documentation or incorrect requirements. I goofed, as simple as that. :)
What I do want to know though is why these requirements exist. I have talked to my contacts at Nutanix and I so far I haven’t got a proper answer to this question.
Can anyone please explain, in detail, why I can’t run Calm on an arbitrary VM?
