[PATCH] virsh: cmdBlockcopy: Remove 'error:' prefix for an empty line
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.
