What do you think might be wrong?

@olivierlambert Yes I do, they are all desktop linux vms.

I am using Xen Orchestra github below.
https://github.com/ronivay/XenOrchestraInstallerUpdater

I have many different Linux machines. They all have xe-guest-utilities installed.
I followed the xcp-ng docs below.
https://xcp-ng.org/docs/guests.html#linux

Ran it to install. On 2 test vms.
sudo apt install xe-guest-utilities-latest

Xen Orchestra show it has the tools installed. (Management agent 7.20.0-9 detected)

Problem Notes:
I am unable to copy my clip board to the machine or to my main pc.

Iso Tools Installing Notes Problems:
Linux Mint tools failed to install coming from the iso download .sh script.
I fixed this by putting in this below to install xe-guest-utilities-latest.

bash /mnt/Linux/install.sh -d $DISTRO -m $MAJOR_VERSION

This failed so I ran. Ubuntu instead.
sudo bash /mnt/Linux/install.sh -d linuxmint -m 20.2

sudo bash /mnt/Linux/install.sh -d ubuntu -m 20.2
It worked and installed fine.
Rebooted the vm.

Found a post below to make sure I am doing the copying correct. I found another post but I don't understand what is Linux with X or Wayland. Did some research and nothing.

How do I get clip board text copying to work on linux? I have tried Debian 10, Linux Mint 20.2. Nothing is working. What am I doing wrong?
