I installed newton version,on 3 multinode platform,one controller,one compute node,and one block storage node,i used the self service network option.But they mentioned in the openstack documentation that the compute and the controller need to have 2 network interfaces,for management and physical provider,i thought maybe i can use just one interface,so i continued with that idea,all seem work fine,i have several instances launched,at first they get an ip address ,and no problem with that,but suddenly i don't get it,they stopped getting an ip address without understanding why. Can this be a problem related to the decision i have made to work with just one interface ?if so,so how the machines were able to get an ip address at first ?
