Integrating Xen 4.2 with Systemd.
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 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, issue:
systemctl enable oxenstored.service
systemctl enable xenconsoled.service
systemctl enable xendomains.service
