Description of problem:
Export host file systems to KVM guests using MTP (Media Transfer Protocol), by using the usb-mtp device in QEMU.
The virtfs project, led by IBM, was never included in RHEL/KVM. It cannot be used as a general passthrough file system due to lack of Windows guest support. There was also some other concerns listed in BZ 729054, including the move MTP as an alternative.
