vic -- VMware VMXnet Virtual Interface Controller device
vic* at pci?
The vic driver provides support for the VMXnet virtual NIC available in
virtual machines by VMware. It appears as a simple Ethernet device but
is actually a virtual network interface to the underlying host operating
This driver supports the vmxnet driver protocol, as an alternative to the
emulated pcn(4) and em(4) interfaces also available in the VMware envi-
ronment. The vic driver is optimized for the virtual machine, it can
provide advanced capabilities depending on the underlying host operating
system and the physical network interface controller of the host.
The vic driver supports VMware virtual NICs provided by the following
o VMware ESX 2.0 and newer
o VMware GSX 2.5 and newer
o VMware Server 1.0 and newer
o VMware Workstation 4.5 and newer
o VMware Fusion 1.0 and newer
The vic driver supports the following media types:
autoselect Enable autoselection of the media type and options. The
driver always uses the fastest available speed and the media
options provided by the underlying host of the virtual
For more information on configuring this device, see ifconfig(8).
The following entry must be added to the VMware configuration file to
provide the vic device:
ethernet0.virtualDev = "vmxnet"
arp(4), em(4), ifmedia(4), intro(4), netintro(4), pci(4), pcn(4), vmx(4),
The vic driver was written by Reyk Floeter <email@example.com> and David
There are tons of bugs in VMware and the underlying host operating sys-
tems. Please consider that the security of the OpenBSD guest can be cir-
cumvented by attacking the host environment.
