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.
[1] https://bugzilla.redhat.com/show_bug.cgi?id=1135169 -- blockcopy job
was cancel by "CTRL+C" while it show there still be one block job in
background
That was against RHEL 7; but I don't know if any Fedora releases suffer
from the same issue.
Right, I looked for a Fedora bug before referring to it. Even the
libvirt master git history refers to this bug with the fixed commit:
commit 8e23e0e977fbcc4a7880e187a63c509d6e6879c6

qemu: fix block{commit,copy} abort handling
When a block{commit,copy} job was aborted on a domain, block job handler
did not process it correctly, leaving a phantom job in the background.
Any further calls to any blockjob causes "block <jobtype> still active"
error. This patch fixes the blockjob handler so that it checks not only
for VIR_DOMAIN_BLOCK_JOB_FAILED status, but VIR_DOMAIN_BLOCK_JOB_CANCELED
status as well, followed by our existing cleanup routine.

I'm working on Debian Wheezy, upgrading to 1.29 libvirt version libvirtd
service doesn't start any more, so at the moment it isn't upgradable....
