SATA Controller Passthrough

[CoralMan]

I've seen a number of threads about this, but want to confirm. I'm trying to move from ESXI to Proxmox as it doesn't work with a Google Coral. On ESXI I have the sata controller passthrough'd to a FreeNAS VM and this has worked great. I figured I would be able to do the same on Proxmox but can't figure it out. I have run the following command. It looks like there is only a single IOMMU group which from reading other threads means there is no way for this to work? Im only making this thread to confirm this as it seems odd that ESXI handles it fine but not Proxmox.

Which command? What is the output of cat /proc/cmdline? Do you run an Intel platform?
Please follow the Proxmox manual and note that for Intel systems you always need to add intel_iommu=on even with kernel 5.15+ (this is a bug in the manual).

If you don't care about security you can search for "ACS override". This will remove PCIe isolation and might not work with every hardware.
