I'm running vagrant with virtualbox on ubuntu 12.04. When the VM isn't running, the system's memory usage is around 2 GB. I've set swappiness at 10% and the VM's memory at 1 GB. When I fire up the VM, strangely, memory usage drops to 1.5GB and I encounter frequent short freezes(because the memory compresses itself?).

Why does this happen?
