IOMMU passthrough HDD

[kssathishmail]

Hi,

I want to learn Proxmox. Did a fresh install to bare metal. Installation and VM creation are successful. Now, trying to Passthrough HDD to VM (Freenas installed). failed to make it work. I have gone through many tutorials, forums, etc to implement/configure IOMMU. But no success. Getting the following message while trying to passthrough the HDD.



Hence, creating this post. Need help. Thanks in advance.

You want to pass a HDD (not an NVMe) through to your VM?
That's not PCI Passthrough then, and doesn't require IOMMU.

Have you seen the following Wiki entry? https://pve.proxmox.com/wiki/Passthrough_Physical_Disk_to_Virtual_Machine_(VM)

use eg , qm set 102 -scsi2 /dev/disk/by-id/ata-xxxxxxxxxxxxxxxxxxxxxxxxxx

first you need to find the disks id by ,"ls -l /dev/disk/by-id" , then which VM to send it too eg 102 , the scsi2 the second drive , if you need more repeat and increase the scsi number .

Thank you so much. I followed your instruction. Added the disks directly to FreeNAS and everything working great.
