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!
