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

53is based on
54.Xr loader 8
55and will present an interface identical to the
56.Fx
57loader on the user's terminal.
58.Pp
59The virtual machine is identified as
60.Ar vmname
61and will be created if it does not already exist.
62.Sh OPTIONS
63The following options are available:
64.Bl -tag -width indent
65.It Fl m Ar mem-size Xo
66.Sm off
67.Op Cm K | k | M | m | G | g | T | t
68.Xc
69.Sm on
70.Ar mem-size
71is the amount of memory allocated to the guest.
72.Pp
73The
74.Ar mem-size
75argument may be suffixed with one of
76.Cm K ,
77.Cm M ,
78.Cm G
79or
80.Cm T
81(either upper or lower case) to indicate a multiple of
82Kilobytes, Megabytes, Gigabytes or Terabytes
83respectively.
84.Pp
85The default value of
86.Ar mem-size
87is 256M.
88.It Fl d Ar disk-path
89The
90.Ar disk-path
91is the pathname of the guest's boot disk image.
92.It Fl h Ar host-path
93The
94.Ar host-path
95is the directory at the top of the guest's boot filesystem.
96.It Fl e Ar name=value
97Set the FreeBSD loader environment variable
98.Ar name
99to
100.Ar value .
101.Pp
102The option may be used more than once to set more than one environment
103variable.
104.It Fl c Ar cons-dev
105.Ar cons-dev
106is a
107.Xr tty 4
108device to use for
109.Nm
110terminal I/O.
111.Pp
112The text string "stdio" is also accepted and selects the use of
113unbuffered standard I/O. This is the default value.
114.El
115.Sh EXAMPLES
116To create a virtual machine named
117.Ar freebsd-vm
118that boots off the ISO image
119.Pa /freebsd/release.iso
120and has 1GB memory allocated to it:
121.Pp
122.Dl "bhyveload -m 1G -d /freebsd/release.iso freebsd-vm"
123.Pp
124To create a virtual machine named
125.Ar test-vm
126with 256MB of memory allocated, the guest root filesystem under the host
127directory
128.Pa /user/images/test
129and terminal I/O sent to the
130.Xr nmdm 4
131device
132.Pa /dev/nmdm1B
133.Pp
134.Dl "bhyveload -m 256MB -h /usr/images/test -c /dev/nmdm1B test-vm"
