Xen users - Jan 2006 - bridges and dummy

Hi List,

step by step getting closer...

If I create three bridges in dom0, do I need to assign in interface (dummy) in
dom0 or is the bridge enough?

Could anybody explain the meaning of the vif definition in the domU config file?
If I specify mac, bridge, ip and vif - what is meant? The mac, ip and vif of
dom0 or domU?

Sorry for mybe trivial questions - but I just don''t understand the
network concept...

cheers,

Mat

The vif you specify in domU config file is the virtual ethernet interface
that dom0 creates. So after launching domU, ifconfig in dom0 will show an
additional interface named vifx.y, inside domU it will appear as eth0 by
default (and not as vif). MAC address that you mention in the vif line in
config file, gets assigned to the new virtual interface (ifconfig in domU
will show that). I am not sure if you can assign IP in config file or not,
haven''t tried it myself. Bridge is a optional feature, you can also do
domU
networking using routing or NAT.
