that only 5% of resources are consumed on Virtualization. This 5% does not linearly increase with the increase of virtual machines. Of course, I still don't believe it ...... 2. When two virtual machines run on the same machine, there is a fair elasticity mechanism (I use them when you don't use them, you use them when I don't use them, and you and I use them for half a minute ), that is, the balloom technology. As for the technology, we need to study it. But we can see the memory balloom fro
