[Rdo-list] I can't get access to VM instances

[Pasquale Salza]

Hi there, I have a lot of problems with RDO/OpenStack configuration.
Firstly, I need to describe my network situation.

I have 7 machine, each of them with 2 NIC. I would like to use one machine
as a controller/network node and the others as compute nodes.

I would like to use the eth0 to connect nodes to internet (and get access
by remote sessions) with the network "172.16.58.0/24", in which I have just
7 available IPs, and eth1 as configuration network on the network
10.42.100.0/42.

This is my current configuration, for each node (varying the IPs on each
machine):

    eth0:
    DEVICE=eth0
    TYPE=Ethernet
    ONBOOT=yes
    BOOTPROTO=static
    IPADDR=172.16.58.50
    NETMASK=255.255.255.0
    GATEWAY=172.16.58.254
    DNS1=172.16.58.50
    DOMAIN=###
    DEFROUTE="yes"

    eth1:
    DEVICE=eth1
    TYPE=OVSPort
    DEVICETYPE=ovs
    OVS_BRIDGE=br-ex
    ONBOOT=yes

    br-ex:
    DEVICE=br-ex
    DEVICETYPE=ovs
    TYPE=OVSBridge
    BOOTPROTO=static
    IPADDR=10.42.100.1
    NETMASK=255.255.255.0
    ONBOOT=yes

I'd like to have instances on 10.42.200.0/24 virtual private network and
the remaining IPs of 10.42.100.0/24 network as floating IPs.

These are the relevant parts of my answers.txt file:

    CONFIG_CONTROLLER_HOST=10.42.100.1

CONFIG_COMPUTE_HOSTS=10.42.100.10,10.42.100.11,10.42.100.12,10.42.100.13,10.42.100.14,10.42.100.15
    CONFIG_NETWORK_HOSTS=10.42.100.1
    CONFIG_AMQP_HOST=10.42.100.1
    CONFIG_MARIADB_HOST=10.42.100.1
    CONFIG_NOVA_COMPUTE_PRIVIF=eth1
    CONFIG_NOVA_NETWORK_PUBIF=eth1
    CONFIG_NOVA_NETWORK_PRIVIF=eth1
    CONFIG_NOVA_NETWORK_FIXEDRANGE=10.42.200.0/24
    CONFIG_NOVA_NETWORK_FLOATRANGE=10.42.100.0/24
    CONFIG_NEUTRON_L3_EXT_BRIDGE=br-ex
    CONFIG_NEUTRON_ML2_TYPE_DRIVERS=vxlan
    CONFIG_NEUTRON_ML2_TENANT_NETWORK_TYPES=vxlan
    CONFIG_NEUTRON_ML2_VNI_RANGES=10:100
    CONFIG_NEUTRON_LB_INTERFACE_MAPPINGS=
    CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=
    CONFIG_NEUTRON_OVS_BRIDGE_IFACES=
    CONFIG_NEUTRON_OVS_TUNNEL_IF=eth1

After the installation, I configure the network like this:

    neutron router-create router
    neutron net-create private
    neutron subnet-create private 10.42.200.0/24 --name private-subnet
    neutron router-interface-add router private-subnet
    neutron net-create public --router:external=True
    neutron subnet-create public 10.42.100.0/24 --name public-subnet
--enable_dhcp=False --allocation-pool start=10.42.100.100,end=10.42.100.200
--no-gateway
    neutron router-gateway-set router public

I'm able to launch instances but I can't get access (ping/ssh) to them.

I don't know if I'm doing something wrong starting from planning.

Please, help me!
