[Bug 1564790] [NEW] blktap2 fails to terminate with filenames containing blanks

[Philipp Hahn]

Public bug reported:

Shutting down a domU with xen-4.1.6.1 doesn't terminate the corresponding blktap2
process, since one (other) VM uses a image file, which contains spaces in its
file name.  /var/log/xen/xend-debug.log has the following information:

Unhandled exception in thread started by
Traceback (most recent call last):
  File "/usr/lib/python2.6/dist-packages/xen/xend/server/BlktapController.py", line 199, in finishDeviceCleanup
    TapdiskController.destroy(path)
  File "/usr/lib/python2.6/dist-packages/xen/xend/server/BlktapController.py", line 289, in destroy
    tapdisk = TapdiskController.fromDevice(device)

    TapdiskController.list())
