I tried this features with oVirt 3.4.1, but it didn't work as expected.

When selecting latest and a guest is shut down it will be deleted.
The expected behavior would be that a new vm with the newest version of 
this template (latest subtemplate) would be started.

The actual behavior is the following: VM will be deleted, pool is 
decreased by 1 vm and vm is started as a standalone (desktop) vm.

So the whole pool features is broken when using latest template feature 
(in 3.4.1 - didn't test it with 3.4.2 yet).
