Yan,
In my opinion, if you are going to spend all the time learning a new
product -- i.e. nova network vs quantum. And if you are only testing a
concept, I would spend it upon Folsom and move from Essex and/or nova
network and nova storage. Quantum eases many of the issues Nova network
has or had, but quantum is the system for support and deployment going
forward.... just my 2 cents...

Hi,
I am trying a proof of concept install of openstack on xen cloud
platform. However, I am a little confused about the network part in
Folsom.
My architecture:
1 Controller node: no Xen, only Ubuntu 12.04, everything for
openstack service except for nova-compute
2 Compute node: XCP 1.6 beta, with nova-compute in special domU
(Ubuntu 12.04), xenapi plugin installed in dom0 already
each node has two NIC, one with public IP (Only limited floating
IP), and another in private network (Any IP is OK)
My goal for network:
flat network or flat dhcp network. I want to use eth0 for public
traffic and service request, and eth1 for inter-vm traffic.
My questions:
1.) does each domU need nova-network running? My understanding is
it's OK to run nova-network individually, but then how to mange the
floating IP globally?
2.) in document for flatdhcp network, I saw four interfaces for
each management domU. Is it OK to have only two interfaces? Say,
eth0-xenbr0 for public IP and services, and eth1-xenbr1 for
VM network?
3.) Is the network isolation rules a must for test install? I
found the patch to vif is still for xenserver 5.6_p2, and can not be
applied to vif of xcp 1.6 or xenserver 6.1, which might be a trouble.
If anyone could help me kindly, it will be quite appreciated, I
have been stuck with install document for several days.
thanks a lot!
