Installing Xen on EndeavourOS Latest

In this tutorial, we will go through the process of installing Xen on an EndeavourOS Latest. Xen is an open-source hypervisor that allows you to create and run multiple guest operating systems on a single physical machine.

Prerequisites

EndeavourOS Latest installed on your system.
A 64-bit processor with Intel VT or AMD-V virtualization support.

Step 1: Update your system

Before we start, it is important to make sure that your system is up to date. Open the terminal and run the following command:

sudo pacman -Syu

Step 2: Install Xen

In EndeavourOS, we can install Xen using the Pacman package manager. Open the terminal and run the following command:

sudo pacman -S xen

This will install Xen and all its required dependencies.

Step 3: Configure GRUB

Now that Xen is installed, we need to configure the GRUB bootloader to allow us to boot into Xen. Open the /etc/default/grub file using your favorite text editor.

sudo nano /etc/default/grub

Add the following line to the file:

GRUB_CMDLINE_XEN_DEFAULT="dom0_mem=512M,max:512M"

This line sets the amount of memory that we want to allocate to the Xen domain-0 virtual machine. You can adjust this value to match your system's specifications.

Save and close the file.

Next, regenerate the GRUB configuration file using the following command:

sudo grub-mkconfig -o /boot/grub/grub.cfg

Step 4: Reboot

Reboot your system, and you should be able to see the GRUB menu. Select the Xen option from the menu, and Xen will start booting.

Step 5: Verify Xen installation

After rebooting, open the terminal and run the following command to verify that Xen is running:

xl info

If everything is working correctly, you should see output similar to the following:
