Trying to set up ipv6 on my ipv4-only virtual host. Was referred to this openvz discussion so downloaded tb-tun and set up /etc/network/interfaces.tail according to the IP addresses I got from tunnelbroker.net. I'm getting these errors, and the tb interface is unusable:
root@tektonic:/etc/network# ifup tb
tun_create: Device or resource busy
root@tektonic:/etc/network# ifconfig tb
tb Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00

Looking at the source now.
