Bug description:
Originally reported in #openstack-nova:
14:44 < lvdombrkr> hello guys, trying to inject admin_password
(inject_password=true ) into image but when creating instance get this error
in nova-compute.log
14:45 < lvdombrkr> 2020-06-06 14:53:50.188 6 WARNING nova.virt.disk.api
[req-94f485ca-944c-40e9-bf14-c8b8dbe09a7b 052d02306e6746a4a3e7e5449de49f8c

Ignoring error injecting admin_password into image (a bytes-like object is
required, not 'str')
14:45 < lvdombrkr> Train + Centos8
Can reproduce on master on devstack by installing python3-guestfs and
setting
[libvirt]
inject_partition = -1
inject_password = true
in nova-cpu.conf. Backtrace after adding a hard "raise" into
inject_data_into_fs():
