Hello all,

in our lab we are trying to integrate Ovirt 4 and OSP.

Actually we have OSP deployed via packstack on the system called neutron.local, a single hypervisor called rhvh.local and hosted engine called rhvm.local.

We correctly added neutron.local as neutron external provider.

The issue we are facing is: trying to poweron a Ovirt vm with neutron network as vnic will fail with "Cannot get interface MTU on "internal-net":No such Device.

Looking via openstack horizon we can see that internal-net has 1500 as MTU.

We also configured the OnlyRequiredNetworksMandatoryForVdsSelection property as true on the Ovirt manager.

What we are missing?

Thank you all for your time

Best Regards

Alessio Dini
