NVMe drives are only supported on host operating systems; NVMe drives are not supported by
guest operating systems. On systems with RHEL 7.3 or later, or Ubuntu 16.04 or later, NVMe
drives can be used as bootable drives. Port 1 of the internal NVMe host bus adapter must be
plugged into NVMe port 1 on the disk drive backplane.
