I think I've hit the same problem that Predrag reported in http://comments.gmane.org/gmane.comp.emulators.libvirt.user/8825.

With libvirt-1.3.2-1.fc23.x86_64 on Fedora 23, when I try uploading an image with vol-upload to a user libvirtd (qemu:///session):

virsh vol-upload --pool default volume.qcow /path/to/file.qcow2

I am getting:

error: Disconnected from qemu:///session due to I/O error error: cannot send data to volume volume.qcow2 error: Cannot write data: Broken pipe

error: One or more references were leaked after disconnect from the hypervisor

If I downgrade to libvirt-1.2.18.2-2.fc23.x86_64 (which is what actually ships in F23), the image upload completes without a problem.

Yes, it's a known bug (and is fixed upstream): https://bugzilla.redhat.com/show_bug.cgi?id=1315606 Rich W.M. Jones informed on IRC a little while ago that the fix for the above bug is included in the current libvirt packages in F24/Rawhide. I've just installed it, and it fixes the bug for me: $ rpm -q libvirt libvirt-1.3.2-2.fc25.x86_64 $ rpm -q libvirt --changelog | head -2 * Wed Mar 09 2016 Richard W.M. Jones <rjones@redhat.com> - 1.3.2-2 - Add fix for RHBZ#1315606. -- /kashyap
