Re: [Xen-users] Need help setting up guest's networking

[Yevgeniy Goldberg <thegoldberg@xxxxxxx>]

Nico,
I did have my firewall turned off.
What would be an example of hard-coding a vif name?
Also, I've discovered that I could manually assign an IP address to a  
vif interface in Dom0.
This way I could network between the Dom0 and DomU, but could not  
establish an Internet connection from the DomU.
My attempt to set the network interface of DomU to dhcp did not work  
either.
Best regards,

-Eugene
