I deployed OpenStack Train using TripleO using this tutorial :
https://kdjlab.com/deploying-rdo-in-a-cohesive-manner/ and the
documentation of TripleO.
I deployed it with DVR.
In my deployment I am using virtual machines with nested-kvm.
The deployment went well, I am using network isolation like this :
- nic1 : provisioning
- nic2 and nic3 (bond0) storage and storage mgmt networks, each one in it's
- nic3 and nic5 (bond1) tenant, api and *external* (10.0.2.0/24 VLAN2100)
networks, each one in it's VLAN
In my physical host (the bare metal KVM) I created a bridge which handles
the provisioning, tenant, api and external networks.
I created a private tenant network (172.16.100.0/24).
openstack network create private
neutron subnet-create private 172.16.100.0/24 --name private-sub
I created a public network and I attached it to the external network using
the same VLAN tag (10.0.2.0/24 VLAN 2100, pool: 10.0.2.100-10.0.2.120) :
*openstack network create --provider-network-type vlan
--provider-physical-network datacentre --provider-segment 2100
neutron subnet-create public 10.0.2.0/24 --name public-sub
--gateway=10.0.2.1 --dns-nameserver 172.16.0.252
I created a vrouter, one port in the public network and the other in the
I created two cirrus instances, each one got it's ip address from the
I found :
cirrus-1 : 172.16.100.81
cirrus-2 : 172.16.100.103
vrouter : 172.16.100.1 private
: 10.0.2.101 external
neutron:dhcp : 172.16.100.2
The problems :
- The instances cannot ping each other.
- The instances cannot ping the vrouter.
- I cannot ping the public vrouter interface.
But both instances can ping neutron:dhcp
Could someone help me dig into this.
Thanks in advance, Regards.
