===> IMPORTANT NOTICES:
In order to complete the installation, and enable Xen,
at the very least you must:
1. If using GRUB2, edit your GRUB2 config files as specified at
https://wiki.archlinux.org/index.php/Xen#Bootloader_Configuration
Support for the grub-mkconfig command was added, and will auto-discover
the deployed xen hypervisor and linux kernel
2. If booting via efi, copy the example /etc/xen/efi-xen.cfg to /boot/xen.cfg
and edit the contents to match the settings you need.
3. Issue the following commands to allow you to create and start VMs:
systemctl enable xen-qemu-dom0-disk-backend.service
systemctl enable xen-init-dom0.service
systemctl enable xenconsoled.service
Other optional services are:
systemctl enable xen-watchdog.service
4. If you want some domains to automatically start up/shutdown, run the following:
systemctl enable xendomains.service
For more information refer to the Wiki:
https://wiki.archlinux.org/index.php/Xen
