Hello, I followed the document to setup my OpenStack environment, using on controller-node, and one compute-node - ( https://github.com/mseknibilel/OpenStack-Folsom-Install-guide/blob/e6e797f991fe79b46c6087e2098d7117ff7b828b/OpenStack_Folsom_Install_Guide_WebVersion.rst . (Please note this is an earlier version of the same document using two nodes).
Following are the ethernet port settings per the doc: controller-node -------------------- eth0 - Mgmt network (assigned by DHCP). eth1 (connected to br-eth1) - VM conf. nework eth2 (connected to br-ex) - VM internet access root@novato:/etc/quantum# cat /etc/network/interfaces # The primary network interface auto eth0 iface eth0 inet dhcp #Not internet connected(used for VM configuration) auto eth1 iface eth1 inet static address 100.10.10.232 netmask 255.255.255.0 #Will generously be bridged to the br-ex later: auto eth2 iface eth2 inet manual up ifconfig $IFACE 0.0.0.0 up up ip link set $IFACE promisc on down ip link set $IFACE promisc off down ifconfig $IFACE down compute node ------------------- eth0 - Mgmt network (assigned by DHCP). eth1 (connected to br-eth1) - VM conf. nework root@bodega:~# cat /etc/network/interfaces # The primary network interface auto eth0 iface eth0 inet dhcp # Not connected to internet auto eth1 iface eth1 inet static address 100.10.10.233 netmask 255.255.255.0 I have a few questions: - On controller-node, is the configuration of eth1 and eth2 switched? I don't understandy why eth1 (for VM access) on both node needs an IP address, and eth2 (for internet access) does not? - Does OVS needs some sort of a (dummy) IP address assigned to a bridge interface (eth1 on controller-node and compute-node). - I can't figure out for the life of me where the 100.10.10.* address for "VM Conf" network came from? Is this a OVS thing? Thank you very much in advance. Regards, Ahmed.
