Usage (hooking up to xhci, other host controllers work -too): - - qemu ${other_vm_args} \ - -drive if=none,id=stick,file=/path/to/file.img \ - -device nec-usb-xhci,id=xhci \ - -device usb-storage,bus=xhci.0,drive=stick - - -Number two is the newer usb attached scsi transport. This one doesn't -automagically create a scsi disk, so you have to explicitly attach one -manually. Multiple logical units are supported. Here is an example -with tree logical units: - - qemu ${other_vm_args} \ - -drive if=none,id=uas-disk1,file=/path/to/file1.img \ - -drive if=none,id=uas-disk2,file=/path/to/file2.img \ - -drive if=none,id=uas-cdrom,media=cdrom,file=/path/to/image.iso \ - -device nec-usb-xhci,id=xhci \ - -device usb-uas,id=uas,bus=xhci.0 \ - -device scsi-hd,bus=uas.0,scsi-id=0,lun=0,drive=uas-disk1 \ - -device scsi-hd,bus=uas.0,scsi-id=0,lun=1,drive=uas-disk2 \ - -device scsi-cd,bus=uas.0,scsi-id=0,lun=5,drive=uas-cdrom - - -Number three emulates the classic bulk-only transport protocol too. -It's called "usb-bot". It shares most code with "usb-storage", and -the guest will not be able to see the difference. The qemu command -line interface is simliar to usb-uas though, i.e. no automatic scsi -disk creation. It also features support for up to 16 LUNs. The LUN -numbers must be continuous, i.e. for three devices you must use 0+1+2. -The 0+1+5 numbering from the "usb-uas" example isn't going to work -with "usb-bot". - -enjoy, - Gerd - --- -Gerd Hoffmann <kraxel@redhat.com> |
