The ostemplates are downloaded only once. So if the total network overhead is exactly the same as if you want to manually deploy the ostemplates on each slave.
Thanks.

Cool, so the initial install of the template copies from CP to slave node, thereafter installs pull locally from /vz/template/cache/ in openvz,
Thanks

I know this is a very old topic, but my idea is along these lines, just a little change. The ostemplate system is very intelligent as is, but I'd like to request a little more intelligence added to it.
My idea is to have a central template cache per data center. I've never seen a need for this until I grew a cluster in a remote data center when you have a good cache on the 1st node in the remote cluster, add a second node, and now the new node is pulling templates from the master which happens to be in another data center, when the templates are most likely already on another node in the same data center.
Then if the requested template does not exist on the remote cluster cache master, revert to the master which will always maintain a full cache, but copy it to the cluster cache master as well since it will be local lan traffic and no cost.
