One thing I’ve noticed is that vimage breaks ppp or there is a bug with vimage (most likely the latter since vimage is still highly experimental).

When an interface (say fxp0) is moved to a vimage (say fxp0, I like naming them the same for the sake of simplicity) ppp simply will not connect to a PPPoE provider  via:

ppp -ddial mtshighspeedinternet

Although one hack that I found was:

1. Boot & login
2. vimage -c fxp0
3. ifconfig fxp0 vnet fxp0
4. ppp -ddial mtshighspeedinternet (which will fail since fxp0 is no longer in the host image)
5. ifconfig tun0 destory
6. vimage fxp0 ppp -ddial mtshighspeedinternet
