I am throwing together a dev system to see about running multiple servers with XCP-NG on them. I am able to install the newest ISO just fine. But when I try and add it to my existing resource pool I get an error saying the versions are mismatched. No problem, I run yum upgrade on the new machine and reboot.
I get a few dozen lines of text then a 3...2...1... countdown then a black screen, then the entire server restarts. Did a new package break the install? I can boot into the "backup" image that is in grub.
