1. setup devstack on XenServer 7.0;
2. create flavor with a ephemeral disk
nova flavor-create --ephemeral 1 test-ephemeral 81 1 1 1
3. Boot VM with the above flavor:
nova boot --image cirros-0.3.5-x86_64-disk --nic net-id=60f82bcc-dfed-4825-8832-4a9331e2df2c --flavor 81 --admin-pass admin --config-drive true testVM2
4. the VM booting will failed with the following traceback:
