Thank you for your nice words!<div><br></div><div>Dual configuration is the most common configuration we use: you only need to be cautious about how to configure the different networks. Just some hints:</div><div><br></div>
<div>1) Leave the management network as simple as possible.</div><div>2) The service network (the one that connects all the virtual machines and nova-network) needs a dedicated NIC (or virtual NIC if you are deploying in a virtual lab with VMware for example) and must be connected to the same group of ports, all with a single VLAN statically assigned to these ports. It's important that nova-network and the virtual machines can see each other.</div>
<div>3) The public network (the one you will use for the floating IPs) cannot be shared with the service network at all. It can be shared with the management network, but normally you can't do real stuff. A good solution is to have a dedicated NIC connected to internet and configured with a public CIDR, or if you are in a corporate environment connect it to the corporate network. Probably you will have to statically assign the port of the switch to the VLAN of the corporate network.</div>
<div><br></div><div>To be honest, most of the complains about the distro has to do with networking, and we can't do a lot about it. We normally try to explain that the single node deployment is like installing a MySQL server for development in 10 minutes -everybody can do it-, but configuring a MySQL server for production highly available is hard. Dual and Multi node deployments can be like deploying the production-ready MySQL: it's not a 10' tasks :-(</div>

Hi,<br>
<br>
For my company, I'd like to set-up a nova-compute All-In-One node, to<br>
replace a eucalyptus cluster which is showing age.<br>
<br>
Unfortunately I'm not well versed in networking, and have trouble<br>
grasping the difference between the multiple network managers, but I<br>
think I would need a Flat mode in my case.<br>
<br>
I have a simple question: could someone please provide a functional<br>
euca.conf, that is using only one NIC, and the relative<br>
/etc/network/interfaces, for Ubuntu 11.10/Diablo?<br>
<br>
Help much appreciated!<br>
<br>
alex<br>
<br>
p.s.: as a side node, I tried everywhere the web for an explanation<br>
of how 'nova-manage network' relates to the flags passed inside<br>
nova.conf.<br>
<br></div></div><div>
