    Integrating Xen 4.2 AUR with Systemd.
    =================================

    I tested the AUR package with a fresh installation of Arch of x86_64. Only
    packages 'base', 'base-devel'and the dependencies mentioned on the site
    were installed.
    * package build also requires dev86
    * dev86 is in multilib, x86_64 users need to enable multilib in /etc/pacman.conf

    * users need to add a new entry to their bootloader config file (mentioned)
    * users need to set up a network bridge or alternative for dom0 (not mentioned)

    The following are what was needed to make systemd work successfully with the AUR package
    (and the installation from xen.org source).

    * Need to include the following line in /etc/fstab:
    none /proc/xen xenfs defaults 0 0

    * Need to include the following line in /etc/fstab:
    none /proc/xen xenfs defaults 0 0

    * Need to place the file 'xendomains' (created in init.d) somewhere useful.
    Fedora use /usr/libexec which Arch does not have. It's a script so maybe
    /etc/xen/scripts/ ?

    * Error messages about 'failed to execute /usr/lib/.... xend/udev_event'
    (lots of them) are caused by /etc/udev/rules.d/xend.rules
    As xend is (a) deprecated and (b) not used, it is safe to remove xend.rules

    I was able to remove /etc/udev/xen-backend rules without any (apparent) effect.

    * The AUR build creates both oxenstored and censtored. oxenstored is more
    efficient according to xen.org so oxenstored.service is provided.

    * The following files integrate Xen 4.2 with systemd 195. They replace xencommons
    which loads startup modules then starts oxenstored, xenconsoled and xendomains.

    To start the services at startup, need to issue:
    systemctl enable oxenstored.service
    systemctl enable xenconsoled.service
    systemctl enable xendomains.service
