BZ:https://bugzilla.redhat.com/show_bug.cgi?id=917702
v2: After discussion in BZ, qemu guys hope the usb-bot(+usb-uas) can be
supported although the absence of its hot-plug feature.
In this patch, libvirt gives an unsupported error in this case.
v1: https://www.redhat.com/archives/libvir-list/2013-September/msg00020.html
And as the missing of hot-plug feature, the replacement of usb-storage is
not a urgent thing. disk attached to usb-storage supports hot-plug/unplug
already.

New subject: [libvirt] [PATCH v2 2/6] qemu: add usb-bot model scsi controller
usb-bot is SCSI HBA which support only one SCSI target with ID 0.
we can create one or more SCSI devices connected to it with -device
as its luns. For usb-bot the limit is 15 luns.
The difference from other SCSI controllers is that usb-bot needs
usb-bus support. That means usb-bot is required to be attached to a
existing USB controller.
libvirt xml example:
<devices>
...
<controller type='usb' index='0'>
</controller>
<controller type='scsi' index='0' model='usb-bot'>
<address type='usb' bus='0' port='1'/>
</controller>
...
</devices>
QEMU commandline should be:
-device piix3-usb-uhci,id=usb \
-device usb-bot,id=scsi0,bus=usb.0,port=1

New subject: [libvirt] [PATCH v2 3/6] qemu: add usb-bot support from disks points of view
usb-bot only supports 16 luns(0~15) and they must be contiguous,
(using lun 0 and 2 without 1 doesn't work). In this case qemu
doesn't throw an error, we can not find the lun 2 in guests. So
Adding a checking function in libvirt to prevent from this case.

v2: After discussion in BZ, qemu guys hope the usb-bot(+usb-uas) can be
supported although the absence of its hot-plug feature.
In this patch, libvirt gives an unsupported error in this case.
v1: https://www.redhat.com/archives/libvir-list/2013-September/msg00020.html
And as the missing of hot-plug feature, the replacement of usb-storage is
not a urgent thing. disk attached to usb-storage supports hot-plug/unplug
already.

An inquiring ping. Shall we support usb-bot right now if its qemu
hot-plug feature is not available yet.
