I would suggest just the opposite, under commit your ram. If your base operating system is Linux, you can create your swap partitions under a host linux tmpfs directory. You can then safely over commit the amount of tmpfs swap space. The guest linux system will expect he swap to be slow, so it

Hello,
I'd like to know if qemu have a tool that let a VM to use more RAM
than it have (when initialised).
Another question is : Can we run run many VM using more RAM than the
RAM installed (on the workstation)? For example I'd like to create 5
VM's who have 256MB (can use 256MB but only
