I cannot find any documentation pertaining to the list of searchable properties of objects (VMs, Hosts, etc) within oVirt / RHEV-M? There is no documentation on this, either in RHEV or oVirt sites (via Google). Can someone provide a list of such attributes?
The code is pretty much self evident, you can simply connect to the SDK with ipython and tab your way through the available options. Of course this doesn't mean better documentation shouldn't be created, I suggest you open a red hat bugzilla request for that.
