Hi, Kirti, 

We decide to go with above type-based interface for KVMGT, with fixed setup 
of attributes too. If both Intel and NVIDIA solutions use such fixed manner,
can we go with a proposal which doesn't include 'class' extension for now?
Later if there is a concrete usage requiring such class-specific attribute 
then it's easy to extend following discussion in this thread. I'm thinking how 
can converge the discussion here into something simple enough (and extensible)
to accelerate upstreaming of both Intel/NVIDIA solutions...
