     virtio_balloon — VirtIO Memory Balloon driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel
     configuration file:

           device virtio_balloon

     Alternatively, to load the driver as a module at boot time, place the following line in

DESCRIPTION

     The virtio_balloon device driver provides support for VirtIO memory balloon devices.

     The memory balloon allows the guest to, at the request of the hypervisor, return memory
     allocated to the hypervisor so it can be made available to other guests.  The hypervisor can
     later signal the balloon to return the memory.

     appeared in FreeBSD 9.0.
