45.Sh DESCRIPTION
46.Nm
47is used to load a
48.Fx
49guest inside a
50.Xr bhyve 4
51virtual machine.
52.Pp

54is based on
55.Xr loader 8
56and will present an interface identical to the
57.Fx
58loader on the user's terminal.
59.Pp
60The virtual machine is identified as
61.Ar vmname
62and will be created if it does not already exist.
63.Sh OPTIONS
64The following options are available:
65.Bl -tag -width indent
66.It Fl c Ar cons-dev
67.Ar cons-dev
68is a
69.Xr tty 4
70device to use for
71.Nm
72terminal I/O.
73.Pp
74The text string "stdio" is also accepted and selects the use of
75unbuffered standard I/O. This is the default value.
76.It Fl d Ar disk-path
77The
78.Ar disk-path
79is the pathname of the guest's boot disk image.
80.It Fl e Ar name=value
81Set the FreeBSD loader environment variable
82.Ar name
83to
84.Ar value .
85.Pp
86The option may be used more than once to set more than one environment
87variable.
88.It Fl h Ar host-path
89The
90.Ar host-path
91is the directory at the top of the guest's boot filesystem.

110respectively.
111.Pp
112The default value of
113.Ar mem-size
114is 256M.
115.It Fl S
116Wire guest memory.

118.Sh EXAMPLES
119To create a virtual machine named
120.Ar freebsd-vm
121that boots off the ISO image
122.Pa /freebsd/release.iso

124.Pp
125.Dl "bhyveload -m 1G -d /freebsd/release.iso freebsd-vm"
126.Pp
127To create a virtual machine named
128.Ar test-vm
129with 256MB of memory allocated, the guest root filesystem under the host
130directory
131.Pa /user/images/test
132and terminal I/O sent to the
133.Xr nmdm 4
134device
135.Pa /dev/nmdm1B
