We may need use try ... except when import since tp-libvirt also need keep compatibility with lower avocado version, eg. 92lts

try :
  from avocado.utils.software_manager import SoftwareManager
except:
   from avocado.utils.software_manager.manager import SoftwareManager

IIUC, avocado-vt and tp-libvirt are intended to be aligned with latest master in other projects. If we want to fix usage on a specific avocado version I think we should introduce releases ourselves instead of adding complexity trying to make the import backwards compatible.

@smitterl ， To make our test stable, we do use avocado lts branch (like lts 92.0) instead of master branch. And we will upgrade to new lts in future.
