Performance comparison between various Hypervisors (dasite.quattrofan.de)

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.

I just can't figure out how to create a VM in ACS with SCSI controllers. I am able to add a SCSI controller to the VM, but the Boot Disk is always connected to the SATA controller. I tried to follow this thread (https://lists.apache.org/thread/op2fvgpcfcbd5r434g16f5rw8y83ng8k) and create a Template, and I am sure I am doing something wrong, but I just cannot figure it out :-(
