This blog covers a hands-on session demonstrating Openstack networking capabilities. This is a followup to my previous blog where I covered the Openstack Icehouse installation and basic usage. I have covered the following in the video.
- Connectivity between VMs in a single subnet.
- Connectivity between VMs across different subnets by having a router between the 2 subnets.
- Connectivity between VMs across 2 different hosts and establish connectivity between the VMs using GRE tunnel between the 2 hosts.
- Using Access security control policies to control access to VM.
VMs used are same as previous blog:
Controller localrc can be found here. Compute localrc can be found here. I had some issues getting connectivity across hosts working with network type vlan and vxlan. I am not clear if the issues are with the ovs switch version that I have or with the localrc configuration. Open vswitch version I am using is 1.4.6.
