Hi,

I am working with OpenStack stable/pike release in Ubuntu 18.04. 

When I am trying to spawn VM, which is worked in the earlier OpenStack releases, VM is stalled with the following log in the VM console logs: 

EFI stub: Booting Linux Kernel... 

EFI stub: Generating empty DTB 

EFI stub: Exiting boot services and installing virtual address map...

I am observing that VM is in Running status, without any error logs. And, VM is booting with UEFI support. But, I am not able to get VM Console.

Earlier I didn't observe this. How can I disable UEFI support, while spawning VM's in OpenStack Nova-Compute.

My Libvirt version is 4.0.0. 

Can someone help me to fix the issue.

Regards, Srikanth.
