Description
===========
Using devstack Rocky with a NVIDIA Tesla M10 + GRID driver on RHEL 7.5.
Profile used in nova: nvidia-35 (num_heads=2, frl_config=45, framebuffer=512M, max_resolution=2560x1600, max_instance=16)
I can launch instances one by one without any issue.
I cannot use --max paramater greater than 1.
Expected result
===============
Be able to use --max parameter
Steps to reproduce
==================
