Hi Kartheeka,
Thanks for visiting here,
To tell you about the requirement, I have seen the crs(hasd stack) itself alone taking 700-800M for 11gr2.
Very Least I can say each VM should have 3GB Ram with 30 (local) and 15(shared disks , ofcourse this is also local) required.
You can find, Nice article on installation for 11gr2 rac using vmware or virtual box is explained very well here.
