-You are not running xen unless you boot xen.
-Possible Xen boot paths:
-EFI boot -> grubx64.efi -> multiboot2 -> [xen.gz, vmlinuz, ramdisk]
-BIOS boot -> grub -> multiboot(2) -> [xen.gz, vmlinuz, ramdisk]
-
-EFI boot -> xen.efi
-
-##########
-grub multiboot2 preparation:
-Install grub: https://wiki.parabola.nu/index.php/GRUB
-
-At this time, some modifications are needed to 20_linux_xen.
-These are included in this package as 21_linux_xen
-
-Set the values needed for your configuration in /etc/default/grub
-Detailed here: https://www.gnu.org/software/grub/manual/html_node/Simple-configuration.html
-Needed:
-GRUB_CMDLINE_XEN
-GRUB_CMDLINE_LINUX_XEN_REPLACE
-These values are not required but can be used; they are appended to the previous values, then this is used for the non-recovery (default) entry:
-GRUB_CMDLINE_XEN_DEFAULT
-GRUB_CMDLINE_LINUX_XEN_REPLACE_DEFAULT
-
-run grub-mkconfig
-
-To boot xen as default:
-suggested: inspect and use this config to boot with. Check if the xen entry works as expected
-find the id of the xen entry and set this as DEFAULT in /etc/default/grub.
-This may look something like:
-GRUB_DEFAULT="xen-gnulinux-simple-a-unique-id-from-your-grub-goes-here"
-
-run grub-mkconfig
-
-##########
-
-Direct EFI boot preperation:
-Create a xen.cfg file in the same directory as xen.efi.
-These need to be in ESP, or in a directory accessible from you EFI bootloader.
-Put settings relevant to your system into xen.cfg
-Detailed here: https://xenbits.xen.org/docs/4.9-testing/misc/efi.html
-Needed:
-kernel
-ramdisk
-Add the xen.efi file to your EFI bootloader (such as Refind).
-And / or add the xen.efi file to you EFI boot options (efibootmgr).

-install_msg() {
- cat << __EOF__
-===> IMPORTANT NOTICES:
-
-In order to complete the installation, and enable Xen,
-at the very least you must:
-1. Configure your bootloader to boot Xen:
-__EOF__
- xen_boot
- cat << __EOF__
-2. 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
-
-3. If you want some domains to automatically start up/shutdown, run the following:
- systemctl enable xendomains.service
-

-Xen 4.9 can now use grub>=2.02 multiboot2.
-If you previously booted using xen.efi, you have an alternative.
-If you previously relied on the packaged 09_xen for grub-mkconfig:
-It is now removed.
-You will need to do the following under grub multiboot2 preparation:
