@hendrik.oosthuizen - That is not the root cause. I am running these on Xeon processors and still have the interface limit. What image are you using? Last image I tried was xrv9k-fullk9-x-6.2.25.qcow2
Hi we had the same problem with VIRL 1.6 which was a new installation. We saw that when you connect with VM there is no IOSXrv 9000 on the node list. And if we used this node type and select IOS XRv 9000 as IOS version it fails (falls in to the admin user setup which is mentioned in the release notes as a bug). After setting up a user, there was a no ethernet interfaces on the device. Then we fetch the node list on VM maestro and than we saw the IOSXRv 9000 as a node. After using the IOSXRv 9000 as a node type there was no problem.
