ACRN Hypervisor Service Module (HSM) is a kernel module which
communicates with ACRN userspace through ioctls and talks to
the ACRN Hypervisor through hypercalls. HSM will only run in
a privileged management VM, called Service VM, to manage User
VMs and do I/O emulation. Not required for simply running
under ACRN as a User VM.
To compile as a module, choose M, the module will be called
acrn. If unsure, say N.
