A couple of minor memory size option related nits: - use common name 'memsize' (instead of 'max-size' or just 'size') - bhyve: update usage with memsize unit suffix, drop legacy "MB" unit - bhyveload: update usage with memsize unit suffix - bhyve(8): document default size - bhyveload(8): use memsize formatting like it's done in bhyve(8) Reviewed by: wblock, grehan Approved by: re (kib), wblock, grehan Differential Revision: https://reviews.freebsd.org/D6952

.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.
|
|
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.
|
|
.Sh OPTIONS
|
|
The following options are available:
|
|
.Bl -tag -width indent
|
|
.It Fl c Ar cons-dev

.Ar cons-dev
|
|
is a
|

|
device to use for
|
|
.Nm
|
|
terminal I/O.
|
|
.Pp
|
|
The text string "stdio" is also accepted and selects the use of
|
|
unbuffered standard I/O. This is the default value.
|
|
.It Fl d Ar disk-path
|
|
The
|
|
.Ar disk-path
|
|
is the pathname of the guest's boot disk image.
|
|
.It Fl e Ar name=value
|
|
Set the
|
|
.Fx
|
|
loader environment variable
|
|
.Ar name
|
|
to
|
|
.Ar value .
|
|
.Pp
|
|
The option may be used more than once to set more than one environment
|
|
variable.
|
|
.It Fl h Ar host-path
|
|
The
|
|
.Ar host-path
|
|
is the directory at the top of the guest's boot filesystem.
|
|
.It Fl l Ar os-loader
|
|
Specify a different OS loader.
|
|
By default
|
|
.Nm
|
|
will use
|
|
.Pa /boot/userboot.so ,
|
|
which presents a standard
|
|
.Fx
|
|
loader.
|
|
.It Fl m Ar memsize Ns Op Ar K|k|M|m|G|g|T|t
|
|
.Ar memsize
|
|
is the amount of memory allocated to the guest.
|
|
.Pp
|
|
The
|
|
.Ar memsize
|
|
argument may be suffixed with one of
|
|
.Cm K ,
|
|
.Cm M ,
|
|
.Cm G

respectively.
|
|
.Pp
|
|
.Ar memsize
|
|
defaults to 256M.
|
|
.It Fl C
|
|
Include guest memory in the core file when
|
|
.Nm
|
|
dumps core.
|
|
This is intended for debugging an OS loader as it allows inspection of
|
|
the guest memory.
|
|
.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"
