I assume you are looking into Lago templates, not oVirt templates?
Currently, I'm not aware of a way. What template do you need?
Side note I cant find a good source of methods available for use in
python-lago-ovirt (or even python-lago). The docs[1] are pretty lacking

If you're referring to the available Lago templates it is described at
[1]. With regard to the lago-ost-plugin(aka python-lago-ovirt), true,
we are lacking some docs there. Also note that for OST it self we have
[2], which has some more OST specific details.
Please elaborate on what you are trying to achieve, we might already
have that feature(but lacking docs, such as 'lago export').

New subject: [ovirt-devel] Lago and vm templates
Thanks for the quick feedback. Didn't realize there was a better mailing
list.
Basically what I'm trying to do is create a big suite of integration tests
for the vagrant provider.
My first attempt of tests basically assumes there's an active ovirt setup
to use and uses secrets to run vagrant configs and assertions. It works but
having a cluster up isn't a good practice.
I'm looking at using bits and pieces from ovirt-system-tests and Lago to
bootstrap a simple cluster (master and single host).
Vagrant requires coming up from a template (and a modified one at that [1].
So I was hoping to use lago and the Lago ost to create a VM (done). Run
things against it (done) then create an ovirt vm template from it (where
I'm currently stuck). That would get me a great place to start running a
matrix of the Ruby sdk versions, vagrant versions, and ovirt versions
(4.0,4.1, etc) to run true integration tests on the vagrant provider.
The issue right now is the lago documentation is pretty scattered and
limited so I'm left cargo culting allot of existing stuff and working off
very limited examples. My suspicion is I'll need to mix and match the ovirt
python sdk and Lago to get the template portion working.
I was surprised to see that the system tests assert alot around VM
creating, snapshotting, stopping, and importing templates, but no tests
around exporting templates

Per cloud-init, I think that's doable. I added support for cloud-init so
Ill see if that can get me going on an easy path.
Per uploading: I'm not sure. This might be pretty complex. Vagrant has a
concept of boxes (for non local files its usually just a zip folder with a
metadata manifest) [1] and uploading to their cloud platform atlas [2] but
that kind of gets outside the realm of Vagrant and more into the niche that
Packer[3] fits.
There has been some work on packer with qemu[4] but not oVirt so possibly
thats a good place for another project to fit (ovirt packer provider)

I was thinking on the following flow that can make oVirt Vagrant feel
much like Vagrant with the libvirt provider (I never tried it with any
other provider, so can`t refer to those) and even mke moving between
the two feel ratehr seamless:
1. User runs 'vagrant up' with a Vagrantfile that teles it to use
the oVirt provider and names a box
2. Vagrant downloads the box from atlas.
3. If the box is a libvirt box, Vargarnt uploads the QCOW2 file
in it to oVirt using the upload API
4. Vagrant launches a VM in oVirt from the uploaded image while
using cloud-init to create /vagrant, inject SSH keys, etc.
I guess a challenge here would be to avoid downloading the same box
more then once if ti was already uploaded to oVirt.
(Sorry for taking your thread off-topic ;)

Regretfully there's something wrong with the cloud-init on the CirrOS image
we download, so it doesn't work well.
Two alternatives I can think of:
1. Download a different image - CentOS and Fedora both work well, for
example. The downside is that it's a bit slow.
2. Upload an image using the upload API. This has the advantage that it's
(1) quicker and (2) will add an additional test to ovirt-system-tests,
which is always a good idea. There's already an example available (
https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/upload...

Downside: will take a bit of space on the git repo, if the image will be on
o-s-t git repo.

Packer support for oVirt is waiting for the Go SDK and for someone to
implement it.

Ive made progress on using pure cloud-init on the centos glance images to
get the vagrant pre-requisites included and usable but so far thats
introduced two issues that still make template exporting within Lago
desirable:
1. Time and network resources to download packages as well as CPU/memory
bloating from repeated installations of the same packages
2. Unable to test network configuration of vagrant, which is a large
part of vagrant to leave untested
1. By that i mean dhcp/static/multiple network interfaces via blocks
such as [1] and [2]
In the mean time I'm contemplating using the vagrant/ruby sdk to make
`vagrant package` export as an oVirt template which would let me call that
in the middle of an ovirt-system-tests suite, if I'm not mistaken?

config.vm.network :private_network,
:ovirt__network_name => 'ovirtmgmt' #DHCP

I think neither, since the patch to do this will not go in any one of
those projects.
Instead it should probably go in ovirt-system-tests which has bugs
tracked in bugzilla.redhat.com (Sorry for the "bureaucracy").
