virt
— rump kernel
virtual network interface
The virt
interface acts as a link between
a rump kernel and a host tap(4)
interface. Interface number <n> always corresponds with the host tap
interface tap<n>. All data sent by virt
is
written into /dev/tap<n> and all data read
from /dev/tap<n> is passed as Ethernet input
to the rump kernel.
A virt
interface can be created and
destroyed in the normal fashion with
ifconfig(8).
The host's tap(4) interface can be further bridged with hardware interfaces to provide full Internet access to a rump kernel.
