Comment 16 for bug 1900800

I've run in to this same issue using an Nvidia RTX A5000, however the Ampere cards present an additional issue. The SR-IOV VFs that the MDEVs use are not persisted after reboot either. I've worked around this by having a system service run before nova-compute to run the sriov-manage command provided by Nvidia to enable the VFs. I used "mdevctl define" to persist the mdev definitions and this has worked for me.
