I'm senior engineer.
I work as a sysadmin for about 25 years (and all you can imagine related to computers) in a town hall, city is about 30.000 citizen.
I started using vmware 4.0, from there we migrate to XenServer 6.5 from there to 7.1. Then once I saw the magic movement of Citrix towards 7.3 and its limits I began to study alternatives.
Basically I was goint to oVirt (Red Hat virtualization open source community solution), and then appeared XCP-ng and I also began to study it.
We have two remote CPD, and in one of them I have the testing machines (3 servers + fibre channel storage), on that one I'm testing XCP-ng 7.4.1 and also XenOrchestra which provides a huge functionality and add-ons to XCP-ng (or XenServer) that are really useful (for example backup-ng).
So, for those advantages I will try to keep on XCP-ng, because it has XO, I don't have to do a lot of VM migration, due XenServer and XCP-ng are 99% identical, and also the community and the professionals, they always try to help you and the software and its characteristics are always evolving and getting better.
I have to way that I really excited about 7.5 XCP-ng because I think is going to be the path to follow.
well, thats all !
thanks for all.
