XCP-ng from Vates in France has over the past 18 months evolved into a very useful platform, rock solid, stable and fast. We won't miss VMware now, Veeam support XCP, others will follow. XCP runs on all the hardware we already have, XOA is easy to manage, it has a good import function from VMware and we're running customer load on it now for almost two years. It's turned into one of those products that "does what it says on the tin". Oliver Lambert, the owner of Vates, deserves an award for what he's done to save ex-VMware customers.
(And no, I've no connection, an almost 20 year VMware user and now very happy 2 year XCP user)
