===> IMPORTANT NOTICES:
In order to complete the installation, and enable Xen,
at the very least you must:
1. Edit your GRUB2 config files as specified at
https://wiki.parabolagnulinux.org/index.php/Xen#Bootloader_Configuration
2. Issue the following commands to allow you to create and start VMs:
systemctl enable xenstored.service
systemctl enable xenconsoled.service
3. If you want some domains to automatically start up/shutdown, run the following:
systemctl enable xendomains.service
4. xen 4.4 no longer includes the xend daemon or the xm binary
For more information refer to the Wiki:
https://wiki.parabolagnulinux.org/index.php/Xen
__EOF__
}
upgrade_msg() {
cat << __EOF__
Note: If you are upgrading from one of the previous 4.2 xen builds, and are having issues
with graphics card passthrough, the default device model used has changed and the
newer model can sometimes have issues. To resolve, add (or change ) the following
line into your domain config file:
device_model_version = "qemu-xen-traditional"
Also remember to rebuild your grub configuration if upgrading from a non-xen 4.4.0
install.
xen 4.4 no longer includes the xend daemon or the xm toolset
This install is now using a new version of the 09_xen file, used when generating
a new grub.cfg file. The new version inherits the default linux-libre kernel command
line settings; to use the old method, uncomment the 'XEN_LINUX_CMDLINE_OVERRIDE'
option in /etc/xen/grub.conf and change the '0' to '1'

===> IMPORTANT NOTICE:
In order to finish removing Xen, you will need to modify
your bootloader configuration files to load your Linux-libre
kernel instead of Xen kernel.
