virtio_balloon — VirtIO Memory Balloon driver


To compile this driver into the kernel, place the following lines in your kernel configura‐ tion file: device virtio_balloon Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): virtio_balloon_load="YES"


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.




The virtio_balloon driver was written by Bryan Venteicher <>. It first appeared in FreeBSD 9.0.
