8 VBoxManage reference
•
--floppy disabled|empty|<uuid>|<filename>|host:<drive>
:
This is the floppy equivalent to the
--dvd
option described above.
disabled
completely disables the floppy controller, whereas
empty
keeps the floppy con-
troller enabled, but without a media inserted.
8.5.3 Networking settings
The following networking settings are available through
VBoxManage modifyvm
:
•
--nic<1-N> none|null|nat|bridged|intnet|hostonly
:
With this,
you can set, for each of the VM’s virtual network cards, what type of net-
working should be available. They can be not present (
none
), not connected
to the host (
null
), use network address translation (
nat
), bridged networking
(
bridged
) or communicate with other virtual machines using internal network-
ing (
intnet
) or host-only networking (
hostonly
). These options correspond
to the modes which are described in detail in chapter
6.2
,
Introduction to net-
working modes

.
•
--nictype<1-N> Am79C970A|Am79C973|82540EM
: This allows you, for
each of the VM’s virtual network cards, to specify which networking hardware
VirtualBox presents to the guest; see chapter
6.1
,
Virtual networking hardware

page
82
.
•
--cableconnected<1-N> on|off
: This allows you to temporarily discon-
nect a virtual network interface, as if a network cable had been pulled from a
real network card. This might be useful for resetting certain software compo-
nents in the VM.
•
With the “nictrace” options, you can optionally trace network traffic by dumping
it to a file, for debugging purposes.
With
--nictrace<1-N> on|off
, you can enable network tracing for a par-
ticular virtual network card.
If enabled, you must specify with
--nictracefile<1-N> <filename>
what
file the trace should be logged to.
•
--bridgeadapter<1-N> none|<devicename>
: If bridged networking has
been enabled for a virtual network card (see the
--nic
option above; otherwise
this setting has no effect), use this option to specify which host interface the
given virtual network interface will use. For details, please see chapter
6.5
,
Bridged networking
, page
86
.
•
--hostonlyadapter<1-N> none|<devicename>
: If host-only networking
has been enabled for a virtual network card (see the –nic option above; otherwise
this setting has no effect), use this option to specify which host-only networking
interface the given virtual network interface will use. For details, please see
chapter
6.7
