Hi,
I have setup my virtual networks with initscripts like in this link:  http://wiki.libvirt.org/page/Networking#Bridged_networking_.28aka_.22shared_physical_device.22.29, but there is no networking whitin any system either between vms or with the host and the vms.
This setup is for kvm, but with Xen in Fedora 8 it works perfect, but xen is now deprecated in Fedora.
This is my setup:
/etc/sysconfig/network-scripts/ifcfg-worknet:
# worknet bridge
DEVICE=worknet
BOOTPROTO=none
BROADCAST=172.16.1.255
#HWADDR=00:50:56:C0:00:01
IPADDR=172.16.1.1
NETMASK=255.255.255.0
NETWORK=172.16.1.0
ONBOOT=yes
TYPE=Bridge
STP=off
DELAY=0
With Xen this alone lets ip traffic pass between host and to allow dhcp and other protocols i have this line in my iptables:
-A FORWARD -i worknet -j ACCEPT
This is the software I'm using:
libvirt-0.4.4-2.fc8
kvm-60-7.fc8


Thanks for your attention.
