HOSTCTL(8) - System Manager’s Manual # HOSTCTL(8) - System Manager’s Manual
NAME # hostctl - display or modify contents of the host’s key-value store
SYNOPSIS # hostctl [-qt] [-f device] [-i input] [-o output] key [value]
DESCRIPTION # The hostctl program provides a generic interface for accessing key-value stores on the system’s host. It is primarily used for an abstracted way to exchange information with hypervisors that are supported by the pvbus(4) subsystem.

NAME # hyperv - Hyper-V guest nexus device
SYNOPSIS # hyperv0 at pvbus?
DESCRIPTION # hyperv driver performs Synthetic Interrupt Controller initialization, sets up hypercalls, and provides access to VMBus services required by paravirtualized devices such as disk and network interfaces.
An access is also provided to the Key-Value Pair exchange interface via pvbus(4). All keys are associated to one of several key pools: Auto, Guest, External or Guest/Parameters.

NAME # pvbus - paravirtual device tree root
SYNOPSIS # pvbus0 at mainbus0
#include <sys/types.h>
#include <sys/ioctl.h>
#include <dev/pv/pvvar.h>
DESCRIPTION # pvbus is used on virtual machines that are running on hypervisors. It provides a pseudo-bus for all paravirtual devices that do not attach to a well-known bus like pci(4). The pvbus driver is responsible for detecting the hypervisor interface, checking the capabilities, attaching the paravirtual devices, and providing access to supported information stores.
