Okay, I have installed the pluging, do you mind explaning how this should work?:
$ grep host /etc/ns* hosts: files libvirt_guest dns
If I'm correct, following your example, I should be able to do:
$ host try06
What am I missing.
'host' does DNS directly, regardless of nsswitch.conf. That's not how majority of SW work. Try:
getent hosts try06
or:
ssh try06
The majority will use gethostbyname() which will consult the nsswitch.conf and use modules defined there. In your case, the /etc/hosts will be consulted first, then libvirt_guest and DNS is used only if everything else failed. You can verify that 'host' does DNS directly by trying a hostname from /etc/hosts. It will give an error even though getent won't.

Thanks for the explanation but it does not seem to work: $ getent hosts try06; echo $? 2 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. -- John Doe
