I am new to openstack and I followed the installation guide of icehouse for ubuntu 12.04/14.04
I chose 3 node architecture. Controller, Nova, Neutron.
The 3 nodes are installed in VM's. I used nested KVM. Inside VM's kvm is supported so nova will use virt_type=kvm. In controller I created 2 nics. eth0 is a NAT interface with ip 203.0.113.94 and eth1 a host only interface with ip 10.0.0.11.
In nova there are 3 nics. eth0 NAT - 203.0.113.23, eth1 host only 10.0.0.31 and eth2 another host only 10.0.1.31
In neutron 3 nics. eth0 NAT 203.0.113.234, eth1 host only 10.0.0.21 and eth2 another hosty only 10.0.1.21 (during installation guide in neutron node i created a br-ex (and a port to eth0) which took the settings of eth0 and eth0 settings are:
auto eth0 iface eth0 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)
Everything seemed fine. I can create networks, routers etc, boot instances but I have this error.
When I launch an instance it takes a fixed ip but when I log in into instance (cirros) can't ping anything. ifconfig with no ip.
I noticed that in demo-net (tenant network) properties under subnet in the ports field it has 3 ports. 172.16.1.1 network:router_interface active 172.16.1.3 network:dhcp active 172.16.1.6 compute:nova down
I searched for solutions over the net but couldn't find anything!
Any help?
Ask me if you want specific logs because I don't know which ones to post!
Thanks anyway!
