Libvirt Autostart

Development
#1

Hey folks,

Currently libvirt hosts created with Foreman do not autostart and Foreman
has no ability to enable autostart. This seems like a poor default to me.
The merge itself should be very simple, just adding ':autostart =>
true/false' to the new host hash.

Would it be better to have hosts autostart by default, or to add a checkbox
for autostart in the host creation page?

+1 for adding it to the form, if it's that easy - to preserve existing
behaviour though, I would default to unchecked.

So it doesn't look like it will be possible. I worked on this some and
setting :autostart => true in the new host's hash is ignored when fog
actually creates the host. I'm unsure why but guessing that since its a new
host there's still no xml file to by symlinked by libvirt till after the
host is fully created. I also can't send the ":autostart => true" after the
host's already created as Fog doesn't let you save libvirt hosts a second
time for fear of duplicates.

I'm working on adding this functionality using foreman_hooks and will write
up a blog post on it later so folks can add it manually if they wish.

Would it be better to have hosts autostart by default, or to add a
checkbox
for autostart in the host creation page?

I created a blog on how to setup autostart for libvirt VMs using
Foreman-hooks. http://www.uberobert.com/autostart-libvirt-vms-in-foreman/

If you've got any recommendations to improve the script let me know.

That's great, thanks for sharing! I've added it to the foreman_hooks
README.
