Re: [Xen-users] advanced bridging...

[Yevgeniy Goldberg <thegoldberg@xxxxxxx>]

Hi Marc,

I saw your recommendation and would like to ask your help in binding  
my DomU network interface to the physical eth1
I have 2 physical interfaces on my host: eth0 (connected to Internet)  
and eth1 (connected to my home 10. network)
I need to be able to have all my DomU to be connected to the eth1 (of  
whatever its virtual representation may be)
Any ideas?

Best regards,

-Eugene
