Adding Physical Disk as Storage Pool with Partitions available for pass through

Hello all. I've been using both Proxmox and KVM/QEMU/LibVirt. Here's my situation...

I have my KVM/Qemu/LibVirt Hypervisor that I would like to convert to Proxmox. I have storage pools that have physical disks setup. The partitions (sd1, sd2, sd3, etc...) on the physical disk show up as "Volumes" section of Virt-manager.

I can pass through each disk partition (Volumes) to any of my VMs as a device Disk. See below...

In order for me to try and migrate from KVM to Proxmox, I need to figure out how to configure Proxmox storage pools to replicate how it is configured in KVM/Qemu/LibVirt. Is there a way for Proxmox to setup a storage pool based on a physical disk that would allow me to use the physical disk's partitions as virtual disks like whats shown above?

Thanks in advanced. Hopefully this is clear enough for someone to help with a solution for Proxmox.

There's no such storage pool available. You can, however, attach any regular block device directly to a VM:

Code:
qm set <vmid> -scsi0 /dev/disk/by-id/xxxxx-partN

(or 'sata0', 'virtio0', whatever floats your boat)

Note that this will break snapshots, migration and to a degree backups.

Excellent! I thought about this route as well but was under the impression I had to pass through the whole disk. Great suggestion. I try this method with using the partition.
