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 Author: Erik Skultety <eskultet@xxxxxxxxxx> Date: Thu Nov 27 13:29:42 2014 +0100 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.
