When a block copy job fails prior to reaching the synchronized phase while we are waiting for the job to finish virsh would print the following: $ virsh blockcopy backup-test vda /tmp/dst.qcow2 --wait --reuse-external --transient-job error: Copy failed The above message looks like we've forgot to print the error message itself as the line ends after 'error:'. Unfortunately with the current API design clients have no way of actually getting the error message as the VIR_DOMAIN_EVENT_ID_BLOCK_JOB(_2) event only reports the status but not an error and the job then vanishes. Fix the expectations by using vshPrintExtra instead of vshError: $ virsh blockcopy backup-test vda /tmp/dst.qcow2 --wait --reuse-external --transient-job Copy failed Note that the newline is required to avoid printing the 'Copy failed' message on the same line when printing the job progress percentage.

If the newline is only needed after the percentage, we should print it based on the verbose parameter, like virshBlockJobWait does with the percentage. Even though we don't have a meaningful error, we should write something generic instead of quietly exiting (although with an error code). Also, the other two functions calling virshBlockJobWait seem to be affected. Jano
