I dont see eth0 ip addr disapper . And what's the ip addr of your first VM
? You are using Nova-network , not Neutron, right ?
And why are you using different route to the same network ?
watrous at watrous-helion:~$ ip route
default via 16.85.144.1 dev eth1
10.11.12.0/24 dev br100 proto kernel scope link src 10.11.12.1
*16.85.144.0/22 <http://16.85.144.0/22> dev eth1 proto kernel scope link
src 16.85.145.6*
*16.85.144.0/22 <http://16.85.144.0/22> dev br100 proto kernel scope link
src 16.85.145.3*
192.168.122.0/24 dev virbr0 proto kernel scope link src 192.168.122.1
