I'm running vbox from the SVN build under root account, so no device group
permission changes have been needed.
Problem:
The guest VM (Debian 4.0) can't interact with the host network interface
(tap0).
- The VM network setting has been set to HOST and menu "Host interface setting
/
interface name" is set to tap0.
- The Linux Host (also Debian) has tap0 created (but unconfigured). It
is running in bridged mode[1]
- The guest[2] has ethernet device eth1, but any attempt to configure with:
ifconfig eth1 .... netmask ...
route ...
produces valid ifconfig and route, but the guest can't send
packets to the Host network. The Host's tap0 settings does not
change with these guest commands.
I understood from the Vbox manual (5.3.3.2.1; end of section) that the
Vbox will interact with the Host system and forward any Guest's
"ifconfig" calls to the tap0 network settings. I'm not trying to
create tap-adapters on the fly with "Setup/Terminate" application
scripts.
Have I understood correctly. What is the missing piece here?
