VMM(4)			 BSD Kernel Interfaces Manual			VMM(4)

NAME
     vmm.ko -- bhyve virtual machine monitor

SYNOPSIS
     To	load the driver	as a module at boot, add this line to loader.conf(5):

	   vmm_load="YES"

     The module	can also be loaded manually with kldload(8):

	   kldload vmm

DESCRIPTION
     vmm.ko provides the kernel	portion	of the bhyve(4)	hypervisor.

     An	Intel CPU with VT-x/EPT	or AMD CPU with	SVM support is required.

     PCI device	passthrough to a virtual machine requires hardware with	VT-d
     support.

PCI PASSTHROUGH
     When the hardware supports	VT-d, and vmm.ko has been loaded at boot time,
     PCI devices can be	reserved for use by the	hypervisor.  Entries consist-
     ing of the	PCI bus/slot/function are added	to the pptdevs loader.conf(5)
     variable.	Additional entries are separated by spaces.  Host PCI devices
     that match	an entry will be assigned to the hypervisor and	will not be
     probed by FreeBSD device drivers.	See the	EXAMPLES section below for
     sample usage.

     A large number of PCI device entries may require a	string longer than the
     128-character limit of loader.conf(5) variables.  The pptdevs2 and
     pptdevs3 variables	can be used for	additional entries.

EXAMPLES
     Reserve three PCI devices for use by the hypervisor: bus 10 slot 0	func-
     tion 0, bus 6 slot	5 function 0, and bus 6	slot 5 function	1.

	   pptdevs="10/0/0 6/5/0 6/5/1"
