Xen Installation

Retrieve Xen source

Clone the Xen repository and switch to the chosen version (i.e., RELEASE4.11):

 $ git clone https://github.com/xen-project/xen.git
 $ git checkout RELEASE-4.11.0 -b RELEASE-4.11.0

In the following part of the tutorial, we refer to the Xen repository path as $XENPATH.

Configure

Configure (for Ubuntu 16.04):

 $ $XENPATH/configure --enable-systemd --libdir=/usr/local/lib64

Configure (for Ubuntu 18.04.01):

 $ $XENPATH/configure --enable-systemd --libdir=/usr/local/lib64

Build and install

Build all components (hypervisor, tools, docs, stubdomains, etc):

 $ cd $XENPATH
 $ make dist

Install (as root):

 # make install

Enable the Xen services Reload dynamic libraries:

 # /sbin/ldconfig

Enable systemd Xen services:

 # systemctl enable xen-qemu-dom0-disk-backend.service
 # systemctl enable xen-init-dom0.service
 # systemctl enable xenconsoled.service
 # systemctl enable xenstored.service
 # systemctl enable xendomains.service

Note that in case of error for enabling xendomains service, remove /etc/init.d/xendomains.

Grub setup

Grub-pc (e.g., Ubuntu 16.04<i>)

Update grub and reboot:

 # udate-grub
 # reboot

Grub-uefi (e.g., <i>Ubuntu 18.04.01</i>) , create the Xen entry for the uefi as follows:

Update grub and reboot:

 # udate-grub
 # reboot
