 7	  ACRN Hypervisor Service Module (HSM) is a kernel module which
 8	  communicates with ACRN userspace through ioctls and talks to
 9	  the ACRN Hypervisor through hypercalls. HSM will only run in
10	  a privileged management VM, called Service VM, to manage User
11	  VMs and do I/O emulation. Not required for simply running
12	  under ACRN as a User VM.
