+One NIC is used by Proxmox as _management port_.<br/>
+This one is given a fixed IP address and bridged from inside the system.

+To allow for disk suspension and SMART checks from the VM, Proxmox needs to **directly** attach the disks to it:

+
+## Disk passthrough
+
+To allow for disk suspension and SMART checks from a VM, Proxmox needs to **directly** attach the disks to it.
+
+Add all SATA disks to the VM with ID 100:
+
+```sh
+$ lsblk -do 'NAME,SIZE,TYPE,MODEL,SERIAL' -I '8'
+NAME  SIZE TYPE MODEL              SERIAL
