Hello,<br><br>i have a setup with a Controller node and two Compute nodes. The topology is as in the figure attached. I followed the hastexo manual <<a href="http://www.hastexo.com/resources/docs/installing-openstack-essex-20121-ubuntu-1204-precise-pangolin" target="_blank">http://www.hastexo.com/resources/docs/installing-openstack-essex-20121-ubuntu-1204-precise-pangolin</a>>, but installing just the modules as described in the figure (attached).<br>
The private network is the nova fixed_range=<a href="http://192.168.22.32/27" target="_blank">192.168.22.32/27</a><br>
The public network is the nova floating_range=<a href="http://10.4.5.32/27" target="_blank">10.4.5.32/27</a><br>I can launch VMs and access them with no problem.<br>But from a VM inside the cloud I cannot access any machine from a range other than the fixed_range (<a href="http://192.168.22.32/27" target="_blank">192.168.22.32/27</a>).<br>
<br>Does anyone know what can it be?<br>How can the controller resolve NAT coming from a node outside the cloud, while cannot resolve coming from a VM in the cloud?<br><br><br>Also, i would like to understand the nova-network setup using flat dhcp.<br>
<br>br100 in controller assumes the ip 192.168.22.33 (from dhcp i guess, different from eth1 that is 192.168.22.1).<br>In the computes, br100 assumes the same ip as the eth1.<br>All nodes have a vrbr0 with the same ip 192.168.122.1, why '.122.'?<br>
<br><br>br100 bridges all the VMs inside a physical server and vrbr0 bridges all br100, is that?<br><br># network specific settings of nova.conf<br>--network_manager=nova.network.manager.FlatDHCPManager<br>--public_interface=eth0<br>
