VIRT(4)                 NetBSD Kernel Interfaces Manual                VIRT(4)


NAME
virt -- rump kernel virtual network interface
DESCRIPTION
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 inter- faces to provide full Internet access to a rump kernel.
