Important note: While installing the Xen utilities using the CD ISO still works, it is outdated and you should prefer installing it using the rpm package. See our post Fedora CoreOS: How to install Xen/XCP-NG guest utilities using rpm-ostree
First, insert the guest-tools.iso supplied with XCP-NG into the DVD drive of the virtual machine.
Then run this sequence of commands to install. Note that this will reboot the CoreOS instance!
curl -fsSL https://techoverflow.net/scripts/install-xenutils-coreos.sh | sudo bash /dev/stdin
This will run the following script:
sudo mount -o ro /dev/sr0 /mnt sudo rpm-ostree install /mnt/Linux/*.x86_64.rpm sudo cp -f /mnt/Linux/xen-vcpu-hotplug.rules /etc/udev/rules.d/ sudo cp -f /mnt/Linux/xe-linux-distribution.service /etc/systemd/system/ sudo sed 's/share\/oem\/xs/sbin/g' -i /etc/systemd/system/xe-linux-distribution.service sudo systemctl daemon-reload sudo systemctl enable /etc/systemd/system/xe-linux-distribution.service sudo umount /mnt sudo systemctl reboot
After rebooting the VM, XCP-NG should detect the management agent.
Based on work by steniofilho on the Fedora Forum.
Please eject the guest tools medium from the machine after the reboot! Sometimes unneccessarily mounted media cause issues.
