The problem is that the certificate chain is just the single server > cert and does not include the intermediate cert or root cert.

If you have a chain of CAs caroot -> child-ca1 -> child-ca2 -> server cert Then the cacert.pem file you create on the clients / server must include the certs for caroot, child-ca1 and child-ca2 all in one file. You can basically just concatenate the .pem files for all the CAs into one file and gnutls will load all the CA cert blocks it finds in that file Regards, Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :| _______________________________________________ libvirt-users mailing list libvirt-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvirt-users
