I would like to change the password of the default login username on Xenial from the image using guestfish

[root@devstack1 ~]# guestfish --rw -a debian-9.1.1-20170725-openstack-amd64.qcow2

Try running qemu directly without libvirt using this environment variable:
export LIBGUESTFS_BACKEND=direct

I moved the images to /var/lib/libvirt/images
as instructed here http://www.cloudkb.net/change-root-password-kvm-qcow2-image/

mv debian-9.1.1-20170725-openstack-amd64.qcow2 /var/lib/libvirt/images/debian-9.1.1-20170725-openstack-amd64.qcow2

Now I got another error:

[root@devstack1 images]# guestfish --rw -a debian-9.1.1-20170725-openstack-amd64.qcow2
