On AlmaLinux, th guest-tool for XCP-ng is provided by a packaged call xe-guest-utilities-latest, which in turns available from the epel-release repository.

The following list a few steps to get XCP-ng guest-tool installed on a VM running AlmaLinux 9.

  1. Enable epel-release repository if not yet enabled by installing a package called epel-release. In my case, the repo has been already enabled.
[root@xoa1 ~]# rpm -q epel-release
  1. Install the guest-tool. If you’re unable to remember the full name of the package, just saerch for ‘xe-guest’.
[root@xoa1 ~]# dnf search xe-guest

[root@xoa1 ~]# dnf install xe-guest-utilities-latest -y

[root@xoa1 ~]# rpm -q xe-guest-utilities-latest
  1. Finally enable and start the xe-linux-distribution service.
[root@xoa1 ~]# systemctl enable --now xe-linux-distribution.service
