I am using virt-manager and created bridge at host .
iface br0 inet static
gateway x.x.x.x[gateway of eth0 earlier]
dns-nameservers x.x.x.x x.x.x.x
with this config
1] net inside host is working
2]net inside vms created using nat is working but i have to manually ser interface file inside the NATD vm.
3] when i create virtualnetwork in routed mode using shared physical device br0 and assign vm to it
the net inside vm not working .
4] created virtual network using only routed mode with any physical device instaead og br0 still net inside vm not working.
I followed documentation on libvirt site .
I want vms indifferent nw should communicate with each other like net1 and vm1 can ping vm2 in net2 .
