Tom,
Where do you store that backed up VM?
With the free version of XO you can’t re-import “orphaned” VM’s that are still on the storage pool. I’ve backed up several to the computer being used to connect to XO, but without XO being installed you can’t put them back into service.
There is something that I don’t remember seeing the last time I started testing XCP-NG, and that is the ability to directly download and install and open sourced version of XO as an “appliance”. This is detailed at the bottom of the ronivay github page:
I don’t remember seeing this back almost a year ago. I’ve been building on a Centos install, but might give this a try as well and see if I can adapt to the Debian based machine. For unknown reason Debian and me do not work well together and Centos seems more logical to me. Not sure why.
