You mentioned that you tried a development version manual. Did you try configuration similar to the example in that manual? https://guix.gnu.org/en/manual/devel/pt-br/html_node/Networking-Setup.html --8<---------------cut here---------------start------------->8--- (static-networking (links (list (network-link (name "bond0") (type 'bond) (arguments '((mode .

"bond0")))) (network-link (mac-address "98:11:22:33:44:56") (arguments '((master . "bond0")))) (network-link (name "bond0.1055") (type 'vlan) (arguments '((id . 1055) (link .
