ODX Requirements
Hyper-V ODX requires hardware to host the virtual hard disk files, connected to the virtual machine as either:
- Virtual SCSI devices
- Directly attached physical disks (also known as pass-through disks)
- Natively attached VHDX-based virtual disks
NOTE: VHD-based or VHDX-based virtual disks attached to a virtual IDE
controller do not support ODX.
