I spent a few days comparing various Hypervisors under the same workload and on the same hardware. This is a very specific workload and results might be different when testing oher workloads.
I wanted to share it here, because many of us run very modest Hardware and getting the most out of it is probably something others are interested in, too. I wanted to share it also because maybe someone finds a flaw in the configurations I ran, which might boost things up.
If you do not want to go to the post / read all of that, the very quick summary is, that XCP-ng was the quickest and KVM the slowest. There is also a summary at the bottom of the post with some graphs if that interests you. For everyone else who reads the whole post, I hope it gives some useful insights for your self-hosting endeavours.
Proxmox does clustering and should have most of the same features. While you are welcome to run whatever you want I think vSphere is getting a bit pricey.
Not even just pricey, but unpurchasable in many cases. Broadcom is really fucking it up
They are just making a living.
In fact, there customers were stealing from them previously.
