Thanks for your reply.
As in the image when I select 1, passthrough turns Active and I'm able to attach the PCI device (which not greyed out) to the VM.
Does the different addresses of the Tesla T4 represent the cores? There are 32 different addresses does that mean that there are 32 cores on the Tesla T4?
If this is the case, will this mean that I've only activated 1 core and have only assigned 1 core the my VM?
i cannot test this because i have installed the nvidia-grid vib on the host and they are active.
just test if you can activate all cores and after reboot if you are able to assign them
When I attempt to activate all cores for passthrough and after the reboot the Tesla T4 card cannot be seen and so adding the PCI device option is greyed out.
Upon rebooting the server again, the Tesla T4 card reappears and the passthrough is disabled on all cores. It's only when I select 1 core i'm able to make the
passthrough active and assign the PCI Device (not greyed out now) to the VM.
Any more ideas?
here is an example that the card was in the wrong pic-slot https://serverfault.com/questions/950161/esxi-tesla-passthrough-enabled-but-not-assignable?rq=1
i am not sure if the card is working without nvidia vib drivers because we have installed them and add a shared pci device to the vm - but therefor you need vcenter and not only a single esxi. i can not test it for you because all hosts with vgpu are productive
maybe its better to ask in the nvidia-forum ? https://gridforums.nvidia.com/
Many thanks for your reply and links.
I have installed the T4 vib drivers on the ESXi host and only then I was able to passthrough and make active 1 address (out of the possible 32).
When I try to passthrough and make active all 32 and try to assign it to the VM, the PCI device option is still greyed out.
This can't be normal can it? I should be able to passthrough all 32 and make active and assign it to the VM?
I've asked the question in the nvidia forum as advised (but no takers as yet) and appreciate all the help and pointers you've give thus far.
