Go to cd <proj root directory>.
In the petalinux-config command, select Image Packaging Configuration > Root filesystem type (INITRD).
In petalinux-config -c rootfs, select PetaLinux Package Groups > Packagegroup-petalinux-xen > [*] packagegroup-petalinux-xen.
Edit the device tree to build in the extra Xen related configs. Edit this file: project-spec/meta-user/recipes-bsp/device-tree/files/system-user.dtsi and add this line: /include/ "xen.dtsi"
It should look like the following:
```
/include/ "system-conf.dtsi"
/include/ "xen.dtsi"
/ {
};
```
Edit the file: project-spec/meta-user/recipes-bsp/device-tree/device-tree.bbapp end and add this line to it: SRC_URI += "file://xen.dtsi"
The file should look like this:
```
FILESEXTRAPATHS_prepend := "${THISDIR}/files:"

SRC_URI += "file://system-user.dtsi"
SRC_URI += "file://xen.dtsi"
```
Run petalinux-build.
The build artifacts are in images/linux in the project directory.

Note: By default, the petalinux-build command does not build Xen. The default root file system does not contain the Xen tools. You have to use Xen RootFS.

Important: You are required to update dom0 memory in xen-bootargs in the xen.dtsi file based on the image/RootFS size. Also, adjust the above load addresses based on the image/RootFS size without overlapping.
