devide resources in openstack
I implement a cloud by openstack. If I have a 20 GB RAM as total cloud Memory and make a flavor with 20G RAM (Just an example :-) ), is it possible to give instances with this flavor to 10 people or just one person?
Actually I want to find a way to use the free resources, when existing instances don't use their max resources. There is this flexibility? is this idea reasonable ??!!
The second question is, there is any way to increase resources automatically when an instance needs?
