networking service not starting with netlink-response-error errno:17

[Giovanni Biscuolo]

Hello,

after a reboot on a running remote host (it was running since several
guix system generations ago... but with no reboots meanwhile) I get a
failing networking service and consequently the ssh service (et al)
refuses to start :-(

Sorry I've no text to show you but a screenshot (see attachment below)
because I'm connecting with a remote KVM console appliance.

The networking service is failing with this message (manually copied
here, please forgive mistakes):

--8<---------------cut here---------------start------------->8---

[...] 11:28 vmunix [...] shepherd [1]: Exception caught while starting
networking: (no-such-device "swws-bridge")


shepherd [1]: Exception caught while staring networking. (%exception
#<&netlink-response-error errno: 17>)

--8<---------------cut here---------------end--------------->8---

The strange thing is that all the configured interfaces: eno1


Please find below the relevant parts of the configuration of my host.

As you can see I've installed a libvirt daemon service (it is working)
with an autostarted (by libvirt) bridge interface named "swws-bridge":
I've tried stopping that bridge (virsh net-destroy...) but the
networking service keeps failing after a "herd restart networking"

Please how can I debug this error?
