vIOMMU enables the option to passthrough pci devices to L2 VMs
in L1 VMs via Nested Virtualisation.
Currently there are two vIOMMU implementation in QEMU to choose:
intel & virtio
virtio-iommu is more recent but less used in production than intel-iommu.
Intel IOMMU:
-machine ...,kernel-irqchip=split
-device intel-iommu
Virtio IOMMU:
-device virtio-iommu-pci

+vIOMMU (emulated IOMMU)
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Using the vIOMMU option allows you to to passthrough PCI devices to layer-2
+VMs in layer-1 VMs via
+https://pve.proxmox.com/wiki/Nested_Virtualization[nested virtualization].
+There are currently two vIOMMU implementations available: Intel and VirtIO.
+
+Host requirement:
+
+* Add `intel_iommu=on` or `amd_iommu=on` depending on your CPU to your kernel
+command line.
+
+Nested virtualization VM requirement:
+
+* Enable *kvm* and use the *host* cpu type to use nested virtualization.
+
+Intel vIOMMU
+^^^^^^^^^^^^
+
+Intel vIOMMU specific VM requirements:
+
+* Whether you are using an Intel or AMD CPU on your host, it is important to set
+`intel_iommu=on` in the VMs kernel parameters.
+
+* To use Intel vIOMMU you need to set *q35* as the machine type.
+
+If all requirements are met, you can add `viommu=intel` to the machine parameter
+in the configuration of the VM that should be able to passthrough PCI devices.
+
+----
+# qm set VMID -machine q35,viommu=intel
+----
+
+https://wiki.qemu.org/Features/VT-d[QEMU documentation for VT-d]
+
+VirtIO vIOMMU
+^^^^^^^^^^^^^
+
+This vIOMMU implementation is more recent and does not have as many limitations
+as Intel vIOMMU but is currently less used in production and less documentated.
+
+With VirtIO vIOMMU there is *no* need to set any kernel parameters.
+It is also *not* necessary to use q35 as the machine type, but it is advisable
+if you want to use PCIe.
+

+# qm set VMID -machine q35,viommu=virtio

Added a proxmoxKVComboBox for selecting a vIOMMU implementation for a
VM. If i440fx is selected, a hint tells that q35 is required for Intel vIOMMU.
The UI also needs to parse the new machine parameter as PropertyString.
