virt
—
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.
