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.
