Thanks for the explanation but it does not seem to work:

$ getent hosts try06; echo $?

Using 'libvirt' or libvirt_guest' one or the other or both does not
change the above, for testing purposes the line 'hosts: ...' has only
libvirt modules.

It is also not working for SSH.

Testing this on Debian Buster (10) ('libnss-libvirt is already the
newest version (5.0.0-4+deb10u1)').

Your help is appriciated.
