Open Stack

Hi Dhastha,

Data interface is just to have connectivity between compute node and
network node. They are the two endpoints of the GRE tunnel formed between
the compute and the network node. If you don't want data-interface, you can
use the management interface as well. You specify that interface in the
quantum openvswitch-agent's file. You can have a look at the detailed
diagram on this site:-

https://github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/blob/OVS_MultiNode/OpenStack_Grizzly_Install_Guide.rst

On your second question that you are unable to ping or ssh the VM, have you
checked that the IP is assigned to the VM properly? Verify it by running
ifconfig on the CLI of the VM. If yes, then kindly check whether the two
conditions added using CLI to security-groups are present in UI. It might
be the security-groups issue or it could be that VM hasn't received IP from
dhcp-server.

-Regards
Rahul Sharma
