In libvirt log file I can see: error : qemuDomainDefineXML:6312 : block copy still active: domain has active block job
Seems like you're hitting an old bug[1] where 'blockcopy' (or 'blockcommit') missed to execute a cleanup routine which destroys a reference to the active block operation -- resulting in the error you're seeing when you attempted to 'abort' the block operation manually.
This bug is fixed in libvirt-1.2.8 and above. I see you're using libvirt-1.2.7, if you can update libvirt in your environment, that should fix your issue.
Are you using a pre-built distro libvirt? If so, which one? We should figure out how to get that vendor to backport the right fix for this issue. Also, I just now committed another related fix; so even the latest 1.2.11 release has an issue where libvirt can get into weird states if parallel block job attempts are made. See commit e1125ce.

That was against RHEL 7; but I don't know if any Fedora releases suffer from the same issue. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
