It would be better to give a user-friendly text to a host device

=> host bind 0 /opt/disk/uboot_sandbox_fat.img
=> efi devices
Device           Device Path
================ ====================
0000000015c1f3a0 /VenHw(e61d73b9-a384-4acc-aeab-82e828f3628b)
0000000015c20f00 /VenHw(e61d73b9-a384-4acc-aeab-82e828f3628b)/Hostdev(0)
