Passthrough physical disk to VM

This guide will passthrough physical disk(s) into a virtual machine and use it like normal disk

This guide uses partial content from the original, summarized based on my understanding and for reference Source: Proxmox Wiki

List the physical disks

In our case, we will use disk-id to identify disks, using lsblk to list your disks installed on the Proxmox host

find /dev/disk/by-id/ -type l|xargs -I{} ls -l {}|grep -v -E '[0-9]$' |sort -k11|cut -d' ' -f9,10,11,12

You will get output like:

/dev/disk/by-id/ata-ST8000DM004-2CX188_ZCT1DNY1 -> ../../sda
/dev/disk/by-id/wwn-0x5000c500c35cd719 -> ../../sda
/dev/disk/by-id/usb-Generic_STORAGE_DEVICE-0:0 -> ../../sdb
/dev/disk/by-id/usb-JMicron_Generic_0123456789ABCDEF-0:0 -> ../../sdc
/dev/disk/by-id/ata-ST2000DX001-1CM164_Z1E783H2 -> ../../sdd
/dev/disk/by-id/wwn-0x5000c500661eeebd -> ../../sdd

Assign disk to VM

After noting your disk by-id from previous step, just assign it to your virtual machine

qm set <vmid> -scsi<scsi_number> /dev/disk/by-id/wwn-0x5000c500661eeebd

Replace <vmid> with your VM ID and <scsi_number> with the running number of scsi on your VM (starting with 0)

Check result

After assigning the disk to the VM, you will see the disk in the Hardware section.

(Optional) Most of the time, I disable backup for the physical disk (for personal reasons) by unchecking the backup option
