Hello,
I have two Openstack nodes (controller & Compute and a Compute). VM's are
getting launched fine on the node that also acts as the controller. But, the
VM's that are scheduled on the compute node seems to go to
error state. I am running Icehouse Master version and my ML2 type driver is GRE
(even VXLAN has the same error) . I used devstack for my installation. If I use
non-tunnel mode and change it to VLAN, I don't see this error and VM's are
launched fine in compute nodes as well.
My devstack configuration on controller/compute is:
Q_PLUGIN=ml2
Q_ML2_PLUGIN_MECHANISM_DRIVERS=openvswitch
Q_ML2_PLUGIN_TYPE_DRIVERS=gre
ENABLE_TENANT_TUNNELS=True
TENANT_TUNNEL_RANGE=32000:33000
The error i see in compute nova screen is:

I did check that the URL seems to be right. The IP address of controller is
specified right and compute can ping the controller.
Any tips/suggestions on what could be wrong?
Thanks,
