Re: [Xen-users] DomU Direct Hardware access

["William Man" <billybahlah@xxxxxxxxxxx>]

When you specify vif, you are creating a virtual interface, not a way to acces the network card.

The setup i have, is the machine has 2 pci network cards.  Both using pci_hide, and i create 2 vif as below:

vif = ['mac=aa:00:00:00:00:13,bridge=dmz','mac=aa:00:00:00:00:12,bridge=intranet']

This means the domU will have 4 eth connections.  2 vritual, 2 physical. It does the routing and is also the dmz server.

Other domUs, I have:

vif = ['mac=aa:00:00:00:00:15, bridge=intranet']

Allowing that machine to have access to the virtual network connection, intranet.

I hope it answers your question.  Someone please correct me, if I'm wrong
