I have deployed Openstack Liberty on Centos 7. I am using Linuxbridge with a provider network. I am seeing a directional performance issue with the VM.

[root@controller ~]# scp -i .ssh/id_rsa CentOS-7-x86_64-GenericCloud.qcow2  centos@8.43.76.12: 
CentOS-7-x86_64-GenericCloud.qcow2                                                                                                 100%   67MB   5.1MB/s   00:13    
[root@controller ~]# scp -i .ssh/id_rsa centos@8.43.76.12:CentOS-7-x86_64-GenericCloud.qcow2 .
CentOS-7-x86_64-GenericCloud.qcow2                                                                                                   3% 2432KB  21.7KB/s   50:33 ETA^CKilled by signal 2.

I have tried everything I can think of, but have not had any effect.

Things I have tried. Set MTU to 1450 Set gro off tso off on the VM and on the compute node interface Upgraded Kernel to 4.4.1-1

The TAP interface reports the speed at 10 Mb / Full. Not sure if this is the cause, but i have been unable to find a way of changing it.

It has to be something easy or in the configuration.

Any help appreciated

For all of those that may see this. I hate when things just do not go as planned. The issue turned out to be a physical network issue. It was a bad ethernet cable.
