.Dt BHYVELOAD 8
.Os
.Sh NAME
.Nm bhyveload
.Nd load a
.Fx
guest inside a bhyve virtual machine
.Sh SYNOPSIS
.Nm
.Op Fl m Ar mem-size
.Op Fl d Ar disk-path
.Op Fl h Ar host-path
.Ar vmname
.Sh DESCRIPTION
.Nm
is used to load a
.Fx
guest inside a
.Xr bhyve 4
virtual machine.
.Pp
.Nm
is based on
.Xr loader 8
and will present an interface identical to the
.Fx
loader on the user's terminal.
.Pp
The virtual machine is identified as
.Ar vmname
and will be created if it does not already exist.
.Sh OPTIONS
The following options are available:
.Bl -tag -width indent
.It Fl m Ar mem-size Xo
.Sm off
.Op Cm K | k | M | m | G | g | T | t
.Xc
.Sm on
.Ar mem-size
is the amount of memory allocated to the guest.
.Pp
The
.Ar mem-size
argument may be suffixed with one of
.Cm K ,
.Cm M ,
.Cm G
or
.Cm T
(either upper or lower case) to indicate a multiple of
Kilobytes, Megabytes, Gigabytes or Terabytes
respectively.
.Pp
The default value of
.Ar mem-size
is 256M.
.It Fl d Ar disk-path
The
.Ar disk-path
is the pathname of the guest's boot disk image.
.It Fl h Ar host-path
The
.Ar host-path
is the directory at the top of the guest's boot filesystem.
.El
.Sh EXAMPLES
To create a virtual machine named
.Ar freebsd-vm
that boots off the ISO image
.Pa /freebsd/release.iso
and has 1GB memory allocated to it:
.Pp
.Dl "bhyveload -m 1G -d /freebsd/release.iso freebsd-vm"
.Sh SEE ALSO
.Xr bhyve 4 ,
.Xr bhyve 8 ,
.Xr loader 8 ,
.Xr vmm 4
.Sh HISTORY
.Nm
first appeared in
.Fx 10.0 ,
and was developed at NetApp Inc.
.Sh AUTHORS
.Nm
was developed by
.An -nosplit
.An "Neel Natu" Aq neel@FreeBSD.org
at NetApp Inc with a lot of help from
.An Doug Rabson Aq dfr@FreeBSD.org
.Sh BUGS
.Nm
can only load
.Fx
as a guest.

			`guest inside a bhyve virtual machine`
			`.Sh SYNOPSIS`
			`.Nm`
Simplify the assignment of memory to virtual machines by requiring a single command line option "-m <memsize in MB>" to specify the memory size. Prior to this change the user needed to explicitly specify the amount of memory allocated below 4G (-m <lowmem>) and the amount above 4G (-M <highmem>). The "-M" option is no longer supported by 'bhyveload' and 'bhyve'. The start of the PCI hole is fixed at 3GB and cannot be directly changed using command line options. However it is still possible to change this in special circumstances via the 'vm_set_lowmem_limit()' API provided by libvmmapi.
