[Libvir] [PATCH] Fix USB device name mis-conversion from S-Expr to XML

[Hiroyuki Kaguchi]

"tablet" and "mouse" are set as a value of the
/local/domain/<domid>/image/hvm/usbdevice,
but libvirt expects "usbdevice" and "usbmouse" as a value.
This causes the following.
If a USB device is attached by virt-manager,
the USB device is not seen from virt-manager.

This patch fixes expected value of libvirt

Thanks,
Hiroyuki Kaguchi
