Dear Gianluca,
Thanks for sharing this information it will take my whole week again to read the architecture and to understand it. By the way is it recommended to run the OpenStack on top of ESXi6 for testing purpose? When I provision the CentOS VMs for this test I append this line 'vhv.enable=true' inside the .vmx file to support Nested-Environment inside my ESXi6
Its my first time to install and configure OpenStack so I'm wondering if I will hit some limitation in my VM environment if I setup this inside of VMs running in CentOS7.2
Yes, in the past I was able to create a nested Openstack "farm" (tested both Grizzly and Icehouse versions) inside VSphere 5 using a vApp without any problems. In this vApp there were 13 VMs configured with CentOS 6: 3 compute nodes, 2 swift proxy nodes, 3 swift storage nodes, 3 controller nodes + 2 load balancer nodes (to manage calls for swift storage and swift proxy nodes) In ESXi 5 the steps to configure/enable nested hypervisors was different than in ESXi 6.
Recently I was able to configure a nested oVirt environment in ESXi 6 and basically I followed what described here. http://nokitel.im/index.php/2016/03/21/nested-windows-hyper-v-server-2012-r2...
and verifying that I was able to load kvm kernel module in my virtual hypervisors and start qemu-kvm on them. HIH, Gianluca
