    IOMMU: difference between "/etc/kernel/cmdline" and "/etc/default/grub"

    I had a roadblock today and figured it out, but I want to understand the difference. I configured now three systems with iommu and pci-passthrough. Everytime appending intel_iommu=on at /etc/kernel/cmdline was enough. Those were on a: ASUS Prime Z590-P MSI MEG Z590 ACE ASUS B450M-K II MSI MEG...

    What are the benefits of PCI passthrough?

    I have a high-level understanding of the PCI passthrough feature of Proxmox, but I'm still wondering what the benefits of it are. My guess is that it helps with approximating a bare metal experience when using a VM with desktop environment? Can anyone elaborate?
