Network interfaces with VMware & Neutron OVS [closed]

Hello, I've configured a multi-node Openstack infrastructure with a controller and two compute nodes. One of the compute node is a basic QEMU and the other one is a VMware compute node using the VMwareESXDriver. On the controller, I have configured Neutron using OpenVSwitch.

Everything works fine with a VM created on the QEMU hypervisor. But when I create a VM with cirrOS on VMware via Openstack, the network interfaces are not recognized by the OS. I can see thanks to Vsphere Client that the VM has a network adapter connected to br-int but nothing in the OS.

I'm wondering if the problem comes from OpenVSwitch. I've read in some docs that OpenVSwitch is not compatible with a VMware compute node. http://docs.openstack.org/grizzly/ope...

However, in this doc, the problem is not raised: http://docs.openstack.org/trunk/confi...

Then, what's your opining? Do I have to change for NVP plugin? Is the problem somewhere else?

Thanks beforehand. Best regards, Romain.

Hello, I've found that my problem was already opened as a bug on launchpad: https://bugs.launchpad.net/cirros/+bug/1239185

It seems that the converted images from QCOW2 to VMDK are not configured well. So I've used an Ubuntu image distributed on this website: https://solutionexchange.vmware.com/store/category_groups/virtual-appliances. The Network Interface boots but I've got another problem. As I use Neutron with GRE Tunnel, the OVS plugin does not work correctly to make my instance get his IP from DHCP. By looking at the TCPDUMP logs, I can see that GRE tunnels are not used from my VM to the network... To solve this problem, you have to use NVP plugin...

Best regards, Romain.
