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.
What I am missing is ESXi/vSphere. Would be quite important for the few people that have access to the eval ressources to set it up.
Same for the BSD versions. I think Beehive?
Sure, ESXi would have been interesting. I thought about that, but I did not test it because it is not interesting to me anymore from a business perspective. And I am not keen of using it in my Homelab, so I left that out and use that time to do something relaxing. It’s my holiday right now :-)
VMware’s predatory practices make wary of their products. I’m avoiding it for all new installs.
Totally fair. Just as a suggestion.
Why do you need vSphere for self hosting?
You ask for a “why deploy this [software]” in this community?
Anyway…Simply: Why not? =)
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.
