Ok, so we’ve done a recent blog post on how to setup XCP-NG Tools on CentOS 7. So this blog post is going to be a rather similar blog post which a few nuances.



You’ll notice that XCP-NG Tools is not installed when you check the Performance tab against your Debian 11 Bullseye virtual machine as you’ll see the message “To view memory data for this VM, you need to install XCP-ng VM Tools”;


Step 1 – Insert the guest-tools.iso in the Virtual Disk

To do this, go into your virtual machine within XCP-NG Centre, then into the Storage tab, then make sure that within your DVD Drive you have the XCP-NG VM Tools is selected;



Step 2 – SSH Into the Virtual Machine

Next step is pretty straight forward, SSH into your virtual machine so you can run the commands to install XCP-NG Tools on Debian 11 Bullseye.


Step 3 – Switch to Sudo

This step is one that isn’t particularly well documented online. As of Debian 10 Buster release and also continued within Debian 11 Bullseye release, to switch to the sudo user you need to run the command;


sudo –




Step 4 – Mount the CD-ROM/DVD Drive

This step is to ensure that your Debian 11 Bullseye can access the contents of the virtual CD-ROM/DVD Drive that we configured within step 1. To do this, simply run the command;


mount /dev/cdrom /mnt/


What the above command is saying is…..Mount the folder path at /dev/cdrom to the folder location /mnt/ – There is nothing more to it than that.


Step 5 – Run the install script for XCP-NG Tools

Now that your Debian 11 Bullseye virtual machine has access to the contents in your virtual CD-ROM/DVD Drive which contains the guest-tools.iso contents, it’s time to run the installation script.


bash /mnt/Linux/


Follow the steps and you’re on your way. You’ll know that XCP-NG Tools has been successfully installed because you’ll get a confirmation message;


And you’ll also note that within the Performance tab against your Debian 11 Bullseye virtual machine that the memory data starts to come through in a matter of minutes at the absolute most, in most cases in about 30 seconds, even without rebooting;




When you follow these simple steps, it’s a few clicks and commands to get XCP-NG Tools up and running on Debian 11 Bullseye via XCP-NG Centre. For every virtual machine that you setup, make sure you install XCP-NG Tools to make your life as easy as possible.
