Tried to install this container but seem to have directory issue

[Bodge-IT]

Running CoreOs as a VM on XCP-NG Xen server with full device PCI passthrough. GPU is a Dell branded Nvidia Quadro P400.

When I run docker run --name=nvidia-drivers -v /:/rootfs --privileged bugroger/coreos-nvidia-driver:2135.5.0-390.77-geforce, I get:

+ ROOT_MOUNT_DIR=/root
+ NVIDIA_DRIVER_VERSION=390.77
+ NVIDIA_DRIVER_COREOS_VERSION=2135.5.0
+ NVIDIA_PRODUCT_TYPE=geforce
+ [[ ! -f /root/etc/os-release ]]
+ error \'File /root/etc/os-release not found, /etc/os-release must be mounted into this container.\'
/install.sh: line 20: error: command not found

So I changed docker run cmd to "-v /:/root" and that seemed to work but when testing for nvidia-smi:
nvidia-smi
-bash: nvidia-smi: command not found

So pretty sure something not right.

Update: OK, so I realised I was getting the loading module issue reported here and after applying @rikatz modprobe fix, my docker build gets past the insert module issue (although not persistent after reboot), but fails with:

Unable to determine the device handle for GPU 0000:00:05.0: Unknown Error
+ umount /lib/modules/4.19.50-coreos-r1/video
+ umount /usr/lib/x86_64-linux-gnu
+ umount /usr/bin

Is this related to my device? I can see:
[INFO 2019-07-22 12:20:24 UTC] Driver compatible! NVIDIA 390.77 (geforce) compiled for CoreOS 2135.5.0
further up in the log. Checking for nvidia:

lsmod | grep -i nvidia
nvidia_modeset       1110016  0
nvidia_drm             16384  0
nvidia_uvm            884736  0

i2c_core               61440  3 nvidia,psmouse,i2c_piix4

but nvidia-smi still unknown in system

I get this in coreos with dmesg

and then this further down...

I also tested the stable-396.44-tesla drivers and get the same issue.

I'm not sure if this a driver issue or XenServer, I've tried so many things but nothing has worked yet
