readline-devel is an optional build dependency; when it is not present, the output of 'virsh <<EOF ... EOF' is different in that the input provided by the user is not echoed, and prompts become interleaved on the same line as actual output, which in turn causes the sed doing prompt filtering to mess up: | ./virsh-snapshot | --- exp 2019-07-31 18:42:31.107399428 -0300 | +++ out.cooked 2019-07-31 18:42:31.108399437 -0300 | @@ -1,8 +1,3 @@ | - | - | -Domain snapshot s3 created from 's3.xml' | -Domain snapshot s2 created from 's2.xml' | -Name: s2 | Domain: test | Current: yes | State: running Maybe we should fix virsh in interactive mode to echo regardless of whether readline-devel was used, but the quicker fix is to make the test use 'virsh "..."' rather than reading its input from stdin.
