1. In a system that includes a host computing machine configured to implement a virtualization intermediary and that includes a physical storage adapter, a method to configure a virtual machine (VM) and a virtual function (VF) of the physical storage adapter to support IO operations to physical storage through a direct path to the VF, comprising:

  • creating a plurality of virtual disks by the virtualization intermediary;

    creating by the virtualization intermediary mapping information that includes a first mapping between virtual disks and physical regions of physical storage and that includes a second mapping between virtual disks and virtual disk addresses;

    allocating by the virtualization intermediary multiple virtual disks to the VM;

    transmitting a copy of the mapping information for the allocated virtual disks from the virtualization intermediary over the physical storage adapter to the VF;

    creating by the virtualization intermediary a virtual port;

    associating the virtual port with mapping information for the allocated virtual disks within the virtualization intermediary;

    binding the virtual port to the VF;

    communicating virtual disk addresses, indicated within the second mapping within the mapping information for the allocated virtual disks, to the VM.
