I have verified this problem on libvirt 1.2.10. I couldn't reproduce with the latest libvirt. After more research, I think the problem was fixed for 1.2.11 with this commit: commit fe3691f66348d55e88c9811fd79ff9314e053977 Author: Erik Skultety <eskultet@xxxxxxxxxx> Date: Wed Dec 3 13:56:47 2014 +0100 qemu: Fix virsh freeze when blockcopy storage file is removed If someone removes blockcopy storage file when still in mirroring phase and then requesting blockjob abort using pivot, virsh cmd freezes. This is not an issue with older qemu versions which did not support asynchronous jobs (which we prefer by default). As we have reached the mirroring phase successfully, polling monitor for blockjob info always returns 1 and the loop never ends. This fix introduces a check for qemuDomainBlockPivot return code, possibly skipping the asynchronous waiting completely, if an error occurred and asynchronous waiting was the preferred method.
