Anthony,
2) When using ifname=eth0, traffic doesn't work from host=>guest nor
from guest=>host. This seems like a major short-coming to me.
Having another networking option that is easy to use but doesn't work
in some fundamental way that a user would expect seems like it's just
going to lead to even further confusion. This patch isn't attractive
to me unless it works just like you were bridging to a physical
interface (and I don't think there's anything fundamental preventing
that).
this works on Win XP. According to the source it seems to need
BIOCFEEDBACK
("This is necessary to connect host and guest.") on BSD. Maybe
something like
this is also needed on your system.
Which OS did you try it with? Linux?
