Hi all,

I am reading the
I got the following deploy architecture. But there are several that I am

   - How and why ip range exist? It is necessary or not? The
   eth1 on the each physical machine own two ip( and Is that possible? In the nova-compute, the eth1 should
   be bridged by br100. the eth1 should not own any IP address, right?
   - In a better way, should we separate the nova-network/eth0 to the
   internet public switch for access the internet by all VMs. and the
   nova-compute/eth0 should be bind to a internal switch for admin access use.
   Is it right?
