pexpect cmd and result.. for FYI

May 31 07:53:14 xtrusia sh[27020]: 2021-05-31 07:53:14 stdout: [info] Seyeong pexpect.send() : b'vol-path 9d2217b0-4433-48a7-9be9-32dc8552c498 --pool maas_guest_lvm_vg

May 31 07:53:14 xtrusia maas.drivers.pod.virsh: [info] Seyeong run : [' ', '<433-48a7-9be9-32dc8552c498 --pool maas_guest_lvm_vg', '/dev/maas_data_vg/9d2217b0-4433-48a7-9be9-32dc8552c498', '']

pexpect should return only /dev/maas_data_vg/9d2217b0-4433-48a7-9be9-32dc8552c498 but it includes part of command as well

I built python 3.6.12 3.7.10 3.8.10 as well and run maas, but there are the same issue.
