I created ext-net and a subnet inside the External Network using the addresses of subnet in which my physical machine exists i.e 10.3.17.0/24 . Then i created a private network and subnet with 192.168.0.0/24. i luanched 2 tiny instances, both pings each other and also the router gateway 10.3.17.151 but not the host 10.3.17.126. Please guide

If you have setup the bridge on the openstack box then do not use the same ip on bridge and on physical NIC network, As a best practice , assign the ip of physical NIC interface to bridge and set the NIC IP to 0. Also check the ip routing table for the default path set on bridge.

ifconfig br-ex x.y.z.a netmask a.b.c.d up
ifconfig eth 0

route -n
the default route should be on br-ex
