I'm using AMD64 Gentoo as the host so to make a chroot environment, I followed 
the Gentoo instructions here:

http://www.gentoo.org/proj/en/base/amd64/technotes.xml?part=2&chap=4#doc_chap3



One problem is the /dev/net/tun device between the host and chroot. The 
qenv-guest script is complaining about no tun%d  device. The errors I'm getting 
are



Connected to host network interface: tun%d

SIOCSIFADDR: No such device

tun%d: unknown interface: No such device

tun%d: unknown interface: No such device

interface tun%d does not exist!

tunconfig: could not launch network script

...



presently I can't seem to create the tun1, tun2, etc... devices
