Hi all,

I installed Fedora 7 RC2 with Xen 3.1. When I created a virtual machine
using Virtual Machine Manager (virt-manager-4.0), Xen 3.1 uses NAT for
virtual network by default, but in Fedora 6 Xen 3.0.3 uses virtual switch by
default. 

I checked the config file for xend: /etc/xen/xend-config.sxp. It was
configured using network-bridge: (network-script network-bridge), not
(network-script network-nat). Because I can get IP address from a DHCP
server so it is not necessary for Xend to provide another NAT.

Could you tell me how to change the virtual network from NAT to a common
virtual bridge (virtual switch)? Thank you.
