.Dd January 22, 2012 .Dt VIRTIO_BALLOON 4 .Os .Sh NAME .Nm virtio_balloon .Nd VirtIO Memory Balloon driver .Sh SYNOPSIS To compile this driver into the kernel, place the following lines in your kernel configuration file: d -ragged -offset indent .Cd "device virtio_balloon" .Ed
p Alternatively, to load the driver as a module at boot time, place the following line in .Xr loader.conf 5 : d -literal -offset indent virtio_balloon_load="YES" .Ed .Sh DESCRIPTION The .Nm device driver provides support for VirtIO memory balloon devices.
p 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. .Sh SEE ALSO .Xr virtio 4 .Sh HISTORY The .Nm driver was written by .An Bryan Venteicher Aq bryanv@FreeBSD.org . It first appeared in .Fx 9.0 .
