[Xen-devel] [PATCH RFC V2 0/5] pvusb toolstack work

[Chunyan Liu <cyliu@xxxxxxxx>]

This patch series is based on Simon's work. Since there is no progress
after last August, I hope we can make this work proceed. Any comment will
be very appreciated.

It adds pvusb toolstack implementation, with pvusb kernel side work,
one could attach/detach a usb device to guest.

Changes to Simon's work:
  - fix format issues
  - fix bind/unbind if usb device has multiple interfaces
  - add codes to update json config when hot add a usb device
  - reorganize and update libxl code to make it more readable.
  - split libxl code into several patches for easier review.
  - remove many unused APIs in libxl_internal.h and libxl.h
  - fix xl command implementation issues (many inconsistences
    between cmdtable and cmdimplementation) and update some
    command syntax
  - remove usb-assigned-list

  Known issues in testing:
  - specify 'usb' in vm config file, then create vm, usb controller state
    keeps in not connected; same result when hot add a usb device in
    vm booting process. But hot adding a usb device after vm is booted,
    works very well.
  - hot adding a usb device to 2.0 usb controller, usb device not working
    well in guest. But adding a usb device to 1.x usb controller, works well.

  These issues are also found with old xend toolstack.
