In December of 2017 when Citrix announced the pricing/feature changes coming with version 7.3, I had finally had enough of XenServer and that is when I started my path to oVirt.
XenServer worked okay for me over the years I used it, however it had many issues that I just got used to and learned to live with.
Now that I have migrated to oVirt, I am loving it! I find that oVirt is much faster, and I am liking the WebUI which I can customize, and I can run it on my mobile devices too!
The documents on this website share what I have learned through migrating from Xen to oVirt as well as some of the tools I have built for oVirt to give back a little. I know these tips will not help everyone, but I hope you are able to get some information that you find helpful.
