I recently switched from Debian as my Dom0 to FreeBSD to make use of ZFS

One of the things I haven't been able to figure out is /etc/xen/auto or
rather /usr/local/etc/xen/auto in FreeBSDs case. It doesn't look like Xen
on FreeBSD ships with any of the configuration options for this feature,
possibly due to lack of support for save and restore.
I don't really need save and restore but auto spawning VMs on boot would be
a nice thing to be able to do without having to write my own rc.d script or
something along those lines.
Is there a way to make use of the auto creation feature on FreeBSD Xen or
is that feature just missing entirely due to the lack of save/restore
If there is no builtin way, I'd appreciate any recommendations for writing
my own scripts to make sure that they're only being run after Xen has been
fully initialized and is ready for xl create commands.
I'm not using Xen right now and I'm afraid I can't remember - which
means it can't have been an issue.
The easy way to kick of something on boot is the traditional
Automation "enthusiasts" like to complicate things and are a bit
disparaging of this simple way of running whatever you want on startup.
The file probably doesn't even exist on your system. So create it. The
contents will look something like:
xl create somemachine.cfg
xl create someothermachine.cfg
xl create yetanothermachine.cfg
echo All done!
This assumes xl is on the search path of the environment when rc.local
is run. I never assume, so I'd use the full path to "xl". Avoid
This is a normal shell script, so you can do more complex things like:
for vm in `ls /usr/something/my-xen-configs` ; do xl create $vm ; done
But this is getting dangerously close to automation ;-)
