Alternatively to IPv4 address:port this will allow to listen on IPv6 link-local (incl. scope), a specific address, or ::. Addresses have to be given in RFC2732 format so that [::]:port parsing will work. This patch also starts to introduce WITH_INET/INET6_SUPPORT to bhyve.

.Sh DESCRIPTION
|
|
.Nm
|
|
is a hypervisor that runs guest operating systems inside a
|
|
virtual machine.
|
|
.Pp
|
|
Parameters such as the number of virtual CPUs, amount of guest memory, and
|
|
I/O connectivity can be specified with command-line parameters.
|
|
.Pp
|
|
If not using a boot ROM, the guest operating system must be loaded with
|
|
.Xr bhyveload 8
|
|
or a similar boot loader before running
|
|
.Nm ,
|
|
otherwise, it is enough to run
|
|
.Nm
|
|
with a boot ROM of choice.
|
|
.Pp
|
|
.Nm
|
|
runs until the guest operating system reboots or an unhandled hypervisor
|
|
exit is detected.
|
|
.Sh OPTIONS
|
|
.Bl -tag -width 10n
|
|
.It Fl a
|
|
The guest's local APIC is configured in xAPIC mode.
|
|
The xAPIC mode is the default setting so this option is redundant.
|
|
It will be deprecated in a future version.
|
|
.It Fl A
|
|
Generate ACPI tables.
|
|
Required for
|
|
.Fx Ns /amd64
|
|
guests.
|
|
.It Fl b
|
|
Enable a low-level console device supported by
|
|
.Fx
|
|
kernels compiled with
|
|
.Cd "device bvmconsole" .
|
|
This option will be deprecated in a future version.
|
|
.It Fl c Op Ar setting ...
|
|
Number of guest virtual CPUs
|
|
and/or the CPU topology.
|
|
The default value for each of
|
|
.Ar numcpus ,
|
|
.Ar sockets ,
|
|
.Ar cores ,
|
|
and
|
|
.Ar threads
|
|
is 1.
|
|
The current maximum number of guest virtual CPUs is 16.
|
|
If
|
|
.Ar numcpus
|
|
is not specified then it will be calculated from the other arguments.
|
|
The topology must be consistent in that the
|
|
.Ar numcpus
|
|
must equal the product of
|
|
.Ar sockets ,
|
|
.Ar cores ,
|
|
and
|
|
.Ar threads .
|
|
If a
|
|
.Ar setting
|
|
is specified more than once the last one has precedence.
|
|
.It Fl C
|
|
Include guest memory in core file.
|
|
.It Fl e
|
|
Force
|
|
.Nm
|
|
to exit when a guest issues an access to an I/O port that is not emulated.
|
|
This is intended for debug purposes.
|
|
.It Fl g Ar gdbport
|
|
For
|
|
.Fx
|
|
kernels compiled with
|
|
.Cd "device bvmdebug" ,
|
|
allow a remote kernel kgdb to be relayed to the guest kernel gdb stub
|
|
via a local IPv4 address and this port.
|
|
This option will be deprecated in a future version.
|
|
.It Fl G Ar port
|
|
Start a debug server that uses the GDB protocol to export guest state to a
|
|
debugger.
|
|
An IPv4 TCP socket will be bound to the supplied
|
|
.Ar port
|
|
to listen for debugger connections.
|
|
Only a single debugger may be attached to the debug server at a time.
|
|
If
|
|
.Ar port
|
|
begins with
|
|
.Sq w ,
|
|
.Nm
|
|
will pause execution at the first instruction waiting for a debugger to attach.
|
|
.It Fl h
|
|
Print help message and exit.
|
|
.It Fl H
|
|
Yield the virtual CPU thread when a HLT instruction is detected.
|
|
If this option is not specified, virtual CPUs will use 100% of a host CPU.
|
|
.It Fl l Op Ar help|lpcdev Ns Op , Ns Ar conf
|
|
Allow devices behind the LPC PCI-ISA bridge to be configured.
|
|

Guest physical memory size in bytes.
|
|
This must be the same size that was given to
|
|
.Xr bhyveload 8 .
|
|
.Pp
|
|
The size argument may be suffixed with one of K, M, G or T (either upper
|
|
or lower case) to indicate a multiple of kilobytes, megabytes, gigabytes,
|
|
or terabytes.
|
|
If no suffix is given, the value is assumed to be in megabytes.

.Pp
|
|

defaults to 256M.

|
|
A display resolution, width and height, respectively.

and maximum is 1920x1200 pixels.

Possible values for this option are

|
(default),

.Dq on

, and
|
|
.Dq off .
|
|
PCI graphics cards have a dual personality in that they are
|
|
standard PCI devices with BAR addressing, but may also
|
|
implicitly decode legacy VGA I/O space
|
|
.Pq Ad 0x3c0-3df
|
|
and memory space
|
|
.Pq 64KB at Ad 0xA0000 .
|
|
The default
|
|
.Dq io
|
|
option should be used for guests that attempt to issue BIOS
|
|
calls which result in I/O port queries, and fail to boot if I/O decode is disabled.
|
|
.Pp
|
|
The
|
|
.Dq on
|
|
option should be used along with the CSM BIOS capability in UEFI
|
|
to boot traditional BIOS guests that require the legacy VGA I/O and
|
|
memory regions to be available.
|
|
.Pp
|
|
The
|
|
.Dq off
|
|
option should be used for the UEFI guests that assume that
|
|
VGA adapter is present if they detect the I/O ports.
|
|
An example of such a guest is
|
|
.Ox
|
|
in UEFI mode.

|
|
.It password
|
|
This type of authentication is known to be cryptographically weak and is not
|
|
intended for use on untrusted networks.
|

Many implementations will want to use stronger security, such as running
|
|
the session over an encrypted channel provided by IPsec or SSH.

General purpose registers can be queried for each virtual CPU, but other

|
|
.Ss Memory
|
|
Memory (including memory mapped I/O regions) can be read by the debugger,

to physical addresses via the current virtual CPU's active address translation.
|

or a similar boot loader before
|
|
.Xr bhyve 4
|
|
can be run.
|
