Then one of my client needs a VM with 32GB RAM and 12 cores , that means vm need resources more than a physical server . So is that possible in ovirt cluster .?  If it is not directly possible is they are any  cloning & Load balancing methods like in amzon auto scaling ?  

not sharing, but overcommit yes. 
if it really needs more RAM than the host has then it's going to swap…well, you may try to use network swap I suppose
performance is not going to be great in any case, obviously.
