lennybtushar, I had this error, I think I've solved it by changing libvirt ot qemu version. Here #link http://52.169.200.208/46/520246/7/check-mlnx-multinode/Nova-ML2-Sriov-Multinode/f90668b/CONTROLLER/env/ you can see environmental files with all relevant packages, I will try to check/find what did I change.09:19
