Kvm networking

[luciany]

I have a local network with a dhcp router connected to ISP.
In a node I have few KVM virtual machines (working fine with NAT). In order to ssh them from the any node inside my local network I need to make bridge networking.
I followed https://help.ubuntu.com/community/KVM/Networking, but no results. Modifying /etc/network/interfaces I loose the net on node and all VMs.
Any better tutor or help, please.
thanks in advance

solution:

I run:
sudo ifconfig eth0 0.0.0.0 up
sudo brctl addbr br0
sudo brctl addif br0 eth0
sudo ifconfig br0 up
sudo dhclient br0 &

if everything goes ok,
run ifconfig and br0 might have an IP allocated

PS: if the router filters MACs don't forget add the new VM one
