neutron setup with virtual interfaces
Hello,
im trying to setup an OpenStack cluster. At the moment, I have three nodes, each node has only one network interface. Following this guide ( http://docs.openstack.org/trunk/insta... + Neutron setup), I do need two NICs for the Compute and three for the network node. At the moment, im using virtual interfaces (ip aliases).
Controller
auto eth0 iface eth0 inet static address 11.0.0.11 netmask 255.255.255.0 gateway 11.0.0.1 dns-nameservers 11.0.0.1 dns-search lan
Network
auto eth0 iface eth0 inet static address 11.0.0.21 netmask 255.255.255.0 gateway 11.0.0.1 dns-nameservers 11.0.0.1 dns-search lan auto eth0:1 iface eth0:1 inet static address 11.0.1.21 netmask 255.255.255.0 auto eth0:2 iface eth0:2 inet manual up ip link set dev $IFACE up down ip link set dev $IFACE down
Compute
auto eth0 iface eth0 inet static address 11.0.0.31 netmask 255.255.255.0 gateway 11.0.0.1 dns-nameservers 11.0.0.1 dns-search lan auto eth0:1 iface eth0:1 inet static address 11.0.1.31 netmask 255.255.255.0
All nodes are connected to a router, which is directly connected to the internet. The router has three IP adresses (Public IP: xxx.xxx.xxx.xxx, LAN: 11.0.0.1 and 192.168.0.1).
As in the guide, I created (via neutron) a external network (ext-net with subnet, CIDR 192.168.0.0/24, IP Allocation Pool 192.168.0.101 - 192.168.0.200, Gateway 192.168.0.1)
and a demo network (CIDR 192.168.2.0/24, IP Allocation Pool 192.168.2.2 - 192.168.2.254, Gateway 192.168.2.1), which are connected via a router (interface router_gateway, IP 192.168.0.101, Status DOWN and Interface router_interface, IP 192.168.2.1, Status ACTIVE).
My Questions/Problems:
1. As the guide states, it should be possible to ping the router gateway (192.168.0.101), but I not able to do so. Wheres my mistake?
2. If I start an instance on the demo-net, I can see on the horizon dashboard that it gets an IP (e.g 192.168.2.16), but the instance itself (running CirrOS) is NOT able to do a dhcp discover and to pick up an IP.
Heres also the output from ovs-vsctl show:
