+## E2E conformance test
+
+It's possible to use QEMU to test the SR-IOV operator on a virtual kubernetes/openshift cluster.
+Using the IGB model network driver allow to create virtual functions on the virtual system
+
+## How to test
+
+First you will need to enable the `DEV_MODE` via the operator environment variable.
+Second step is to add the intel virtual nic to the supported nics configmap.
+
+```
+Intel_ixgbe_82576: 8086 10c9 10ca
+```
+
+Another requirement is to load the vfio kernel module with no_iommu configuration. Example systemd:
+
+```
+[Unit]
+Description=vfio no-iommu
+Before=kubelet.service crio.service node-valid-hostname.service
+
+[Service]
+# Need oneshot to delay kubelet
+Type=oneshot
+ExecStart=/usr/bin/bash -c "modprobe vfio enable_unsafe_noiommu_mode=1"
+StandardOutput=journal+console
+StandardError=journal+console
+
+[Install]
+WantedBy=network-online.target
+```
+
+# TBD
