    Did you get any resolution from VMware? This is exactly what we’re seeing. We have 4 VM’s that need 1TB of vRAM and a 6.4TB NVMe PCI passthrough

    • Actually, I did report the issue to VMware but they didn’t answer me.
      Also it’s depended to hardware because I could assign more memory to virtual machines when I was using HPE DL580 G8.
      But I couldn’t assign more than 800GB memroy to virtual machines when they are hosting on Oracle X4-8.
      I suggest you, try difference solutions without Pass-Through.
      If you get solution, please share with me.
