I am planning to perform nested virtualization with GPU device. I have guest Ubuntu OS running and I have mapped GPU to it by enabling intel_iommu on the host, and configuring NVIDIA PCI as vfio-pci device. I am also able to install NVIDIA driver on the guest and use it for deep-learning.

However, now I want to run another VM inside the guest, let's call the guest that runs on host as L1 and the guest that runs on guest as L2, I want the GPU to be accessiable by the L2 guest, I came across vIOMMU supported on Q35 Qemu chipset, how do I enable IOMMU on L1 guest, so that I can pass the gpu directly to L2 guest??

virt-manager, as a simple graphical interface, does not support many advanced features of the underlying virtualization platform.

To do what you want, you need to tap into libvirt or even custom qemu command line options.
