Xen is a powerful hypervisor that enables users to run multiple virtual machines on a single physical machine. In this tutorial, we will guide you through the process of installing Xen on a Fedora Server Latest.
Before we begin, make sure your system meets the following prerequisites:
Before installing Xen, it is essential to update the system to the latest version. Open a terminal and run the following command to update the packages:
sudo dnf update -y
Next, install the necessary packages for Xen on your Fedora server. Run the following command:
sudo dnf install -y xen libvirt libvirt-python libvirt-client virt-install virt-manager bridge-utils
To boot into the Xen hypervisor, you need to configure GRUB. Open the /etc/default/grub file in your favorite text editor and set the default kernel to Xen by adding the following line:
GRUB_DEFAULT="Xen 4.4.4-31.fc22.x86_64"
Save the file and run the following command to update the GRUB configuration:
sudo grub2-mkconfig -o /boot/grub2/grub.cfg
The libvirtd daemon manages virtualization applications for Xen. Enable and start the service using the following command:
sudo systemctl enable libvirtd
sudo systemctl start libvirtd
To allow your virtual machines to communicate with your network, you need to create a network bridge. First, disable the default network interface by running the following command:
sudo nmcli c down enp0s3
Next, create the network bridge by running the following command:
sudo nmcli c add type bridge ifname br0
sudo nmcli c add type bridge-slave ifname enp0s3 master br0
sudo nmcli c modify br0 ipv4.addresses 192.168.50.100/24
sudo nmcli c modify br0 ipv4.gateway 192.168.50.1
sudo nmcli c up br0
This creates a bridge named br0 that is associated with the enp0s3 network interface. We also assigned an IP address to the bridge to allow it to connect to the Internet.
Now that Xen is installed and configured, you can start creating virtual machines. Use the following command to install a virtual machine:
sudo virt-install \
--name vm1 \
--memory 2048 \
--vcpus 2 \
--disk size=10 \
--cdrom /path/to/iso/file \
--network bridge=br0 \
--graphics vnc,port=5900 \
--virt-type xen
Replace vm1 with the name of your virtual machine and /path/to/iso/file with the location of the ISO file you want to install. This command will create a virtual machine with 2 CPUs, 2 GB of RAM, a 10 GB disk, and a VNC graphical interface.
Congratulations! You have successfully installed Xen on your Fedora Server Latest. You can now create and run multiple virtual machines on a single physical machine using the Xen hypervisor. Have fun!
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
