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 had a rough start with XCP-ng too. One issue I had was the NIC in my OptiPlex, which worked... but was super slow. So the initial installation of the XO VM (to manage XCP-ng) took over an hour. After using a USB NIC with another Realtek Chip, Networking was no issue anymore.

For management, Xen-Orchestra can be self-built and it is quite easy and works mostly without any additional knowledge / work if you know the right tools. Tom Lawrence posted a Video I followed and building my own XO is now quite easy and quick (sorry for being a YT link): https://www.youtube.com/watch?v=fuS7tSOxcSo
