<div style="word-wrap:break-word"><div></div><div>- What is good practice to run compute node? I mean do I need nova-volume, nova-cert and nova-scheduler on each compute node? </div></div></blockquote><div><br>You only need nova-compute for ec2 usage on each node. nova-volume is needed if you intend to create volumes on those nodes. <br>

<div style="word-wrap:break-word"><div><br></div><div>- Do I need to create a bridge on the new compute node, when I don't want to run nova-network on that node? I think bridge is only required by the nova-network? But than I get confused with how the network will work? I mean all the traffic of the VMs will go from the node running nova-network? I guess this is not correct right? </div>
<div><br></div></div></blockquote><div><br>Depends on how your networking is set up. But usually a bridge is created for each virtual interface of your instances. nova-compute will do that for you.<br> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<div style="word-wrap:break-word"><div></div><div>If all the traffic from VMs will route through the node running nova-network then should I run nova-network on each compute node as well? Or what is the correct way? </div>
<div><br></div></div></blockquote><div style="word-wrap:break-word"><br>depends on your networking configuration. <br><div>Thanks in advance. </div><br></div></div>
