VMs are great, they allow you to consolidate many computers in to 1 physical system without forcing you to use a single OS. Sometimes it’s nice to give these VMs access to HW directly. In this guide I’ll show you how to pass a disk, at the block level through to a VM in Proxmox. This isn’t passing the disk through directly so it’s not a good idea to use ZFS or raid on the passed through disks. You’ll notice they still show as a VirtIO device inside the VM.
