Hi,
I made the patch that corrected the following problem.
It is that when I executed the "virsh detach-disk" command on Xen3.3.1,
Libvirt could not detach tap device and output the following error
message.
# virsh detach-disk Fedora xvdd
libvir: Xen Daemon error : POST operation failed: xend_post: error
from xen daemon: (xend.err 'Device 51760 not connected')
The cause of this problem is incompatible of Xen3.3.0 and Xen3.3.1.
I think Xen specific was changed by the following patch.

If you have any comments, please suggest me.
