Comment 8 for bug 1847361

Known mitigation options at this point:
- live migrate for upgrades
  - prohibited by SR-IOV usage
  - Tech to get SR-IOV migratable is coming (e.g. via net_failover, bonding in DPDK, ...)
- load the modules you need in advance
  - Note: lacking an explicit "load module" command makes this slightly odd for now
  - but using iscsi or ceph is never spontaneous, a deployment has or hasn't the
    setup to use those
  - Create a single small read-only node and attach this to each guest, that will
    load the driver and render you immune to the issue. While more clunky, this isn't
    so much different than how it would be with an explicit "load module" command.
