35.Fl -vm= Ns Ar <vmname>
36.Op Fl -create
37.Op Fl -destroy
38.Op Fl -get-stats
39.Op Fl -inject-nmi

44.Sh DESCRIPTION
45The
46.Nm
47command is a control utility for active
48.Xr bhyve 8
49virtual machine instances.
50.Pp
51.Em Note :
52Most
53.Nm
54flags are intended for querying and setting the state of an active instance.
55These commands are intended for development purposes, and are not documented here.
56A complete list can be obtained by executing
57.Nm
58without any arguments.
59.Pp
60The user-facing options are as follows:
61.Bl -tag -width ".Fl d Ar argument"
62.It Fl -vm= Ns Ar <vmname>
63Operate on the virtual machine
64.Ar <vmname> .
65.It Fl -create
66Create the specified VM.
67.It Fl -destroy
68Destroy the specified VM.
69.It Fl -get-stats

73.It Fl -force-reset
74Force the VM to reset.
75.It Fl -force-poweroff
76Force the VM to power off.
77.It Fl -checkpoint= Ns Ar <filename>
78Save a snapshot of a virtual machine.
79The guest memory contents are saved in the file given in
80.Ar <filename> .
81The guest device and vCPU state are saved in the file
82.Ar <filename>.kern .
83.It Fl -suspend= Ns Ar <filename>
84Save a snapshot of a virtual machine similar to
85.Fl -checkpoint .
86The virtual machine will terminate after the snapshot has been
87saved.
