<br>
Currently we are working on feature component registry [1] which should<br>
help us to prevent not logical compositions of different components in<br>
wizard tab during cluster(environment) creation. Now we have a mechanizm<br>
of 'restrictions' which is not flexible for components provided by<br>
plugins. In our current approach we have two states for components -<br>
compatible/incompatible which are described in compatibility matrix<br>
based on OpenStack components (For example: cinder-vmware storage only<br>
compatible with vCetner hypervisor and should work when only KVM uses).<br>
In this case we allow user to choose only that components we defently<br>
know works well with each other. Another approach tell us to have 3<br>
states: compatible/incompatible/ and all other components about<br>
compatibility with others we know nothing. In that case we should show<br>
on wizard which components compatible, which not, and others which user<br>
can enable on his own risk. So I need your opinions: should we allow for<br>
user choose only that coponents which are tested and defently works or<br>
prevent her/him from choosing which are defently not works and means<br>
potentional risk of failing deployment when component about we know<br>
nothing isn't work together.<br>
