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 ...
The solution to this issue is to enable IOMMU in your GRUB boot parameters. You can do this by setting the following in /etc/default/grub GRUB_CMDLINE_LINUX_DEFAULT="intel_iommu=on" If you're using an AMD processor, you should append amd_iommu=on to the boot parameters instead GRUB_CMD...
To keep things simple, I suggest plugging the GPU you wish to access from a VM into the fastest PCIe x16 slot, as this one typically has its own IOMMU group. In most cases, it should be the first x16 socket on the motherboard. Then, you can insert your secondary graphics card into ...
In short, when running a recent hypervisor kernel, AVIC can be enabled by loading thekvm_amdmodule withavic=1. All KVM guests will then enable both SVM and IOMMU AVIC functionality, unless restricted via kernel parameters or inhibited due to specific guest configurations that are not supported b...
Enable IOMMU for L0: Before we can proceed, we'd need to make sure the L0 hypervisor (bare-metal PVE) has IOMMU enabled, which can be done by tuning the kernel command-line parameter. As mentioned in Proxmoxdocumentation, you need to addintel_iommu=onin the bootloader configuration file...
To enable IOMMU on the kernel for Intel processors, pass "intel_iommu=on" boot parameter on your Linux. Followthis tutorialto find out how to add a kernel boot parameter via GRUB. After configuring the boot parameter, reboot your host. ...

On our development board, we are trying to burn the iMX93 M33 core program to eMMC using the UUU tool. however, there are some problems in the process. Background of the problem:1. Have taken boot image and imx-mkimage source repository from iMX93 Linux BSP version and p...
Now I evaluating i350-T2 on same machine and I double checked BIOS -- SR-IOV global setting is "enable". I boot system with "intel_iommu=on" kernel parameter. Any idea why i350-T2 device does not report its SR-IOV capability? Can I check it in EEPROM? Thanks for your help, Igor...
