.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
|

|
|
.Fx
|
|
loader on the user's terminal.
|
|
This behavior can be changed by specifying a different OS loader.
|
|
.Pp
|
|
The virtual machine is identified as
|
|
.Ar vmname
|
|
and will be created if it does not already exist.
|
|

|
|
.It Fl h Ar host-path
|
|
The
|
|
.Ar host-path
|
|
is the directory at the top of the guest's boot filesystem.
|

|
|
.It Fl S
|

Wire guest memory.
|
|
.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"
|
|
.Pp
|
|
To create a virtual machine named
|
|
.Ar test-vm
|
|
with 256MB of memory allocated, the guest root filesystem under the host
|
|
directory
|
|
.Pa /user/images/test
|
|
and terminal I/O sent to the
|
|
.Xr nmdm 4
|
|
device
|
|
.Pa /dev/nmdm1B
|
|
.Pp
|
|
.Dl "bhyveload -m 256MB -h /usr/images/test -c /dev/nmdm1B test-vm"
