Ubuntu OpenStack - can't create VMs

OpenStack from Canonical/Ubuntu repo. (One Compute/Controller_All-in-One node and additional compute node = total of 2).

Let me know if any more logs would help.

Seems whether VMs are created in controller/compute or additional compute, they can't get out of spawn/error mode. I wonder if networking is at least fine.

Thanks.

Ubuntu OpenStack - can't create VMs

OpenStack from Canonical/Ubuntu repo. (One Compute/Controller_All-in-One node and additional compute node = total of 2).

Let me know if any more logs would help.

Seems whether VMs are created in controller/compute or additional compute, they can't get out of spawn/error mode. I wonder if networking is at least fine.

Thanks.

Ubuntu OpenStack - can't create VMs

Let me know if any more logs would help.

Seems whether VMs are created in controller/compute or additional compute, they can't get out of spawn/error mode. I wonder if networking is at least fine.

Thanks.
