    Hi Everyone,
    Is there any information about Memory Address Limit for proxmox?
    VMware has it described below.
    ://kb.vmware.com/s/article/2087943

    I am having issue trying to pass through 8x Tesla GPUs to a VM on ovmf bios and suspecting could be related to settings in BIOS.
    All 8 GPUs can be listed under lspci but memory could not be allocated to BAR.

    Any suggestion is appreciated. Thanks.

    Some updates.

    Apparently I have better luck with SeaBIOS, managed to get 8 gpus passthrough correctly on a 256GB RAM VM.
    Correctly as in nvidia-smi showing all the gpus.

    Unfortunately I have issue if I set the VM's RAM higher ( => 512GB)

    Will share here if I find out more.
