A xen host memory ballooning daemon

squeezed: a xen host memory ballooning daemon

Squeezed uses ballooning to move memory between running VMs. It is able to:

1. avoid wasting host memory: unused memory can be gifted to VMs
2. share memory according to a configured policy, so some VMs will use more than others
3. "squeeze" existing VMs to make room to start new VMs.

Squeezed is an optional component of the xapi toolstack.
