That's normal. If you boot the replicated VMs, then blocks will be changed. It mean no further delta replication will work on this VM. Force boot it if you lost the original VM and you don't care about delta toward the copy anymore. If you just want to test the VM without doing a new full (breaking the delta chain), boot with a copy. I think I explained that in this video: https://www.youtube.com/watch?v=FfUqIwT8KzI
That's a display glitch.
In case someone ran into the same problem here is how I solved it.
I had a feeling this was http mounts issue. I checked and looks like during update process the .xo-server.toml got deleted. I copied the sample one from the /opt/xen-orchestra/packages/xo-server/sample.config.toml , edited the http.mount and bob's your uncle.
I have a feeling this has something to do with the format of that file change. When I originally built from source the file has a slightly different syntax and it was called .xo-server.yaml. At least according tot he directions I used to build. In any case its all back to normal now.
Thanks you everyone for your help.
