.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
