If I use the workaround described in https://bugs.gentoo.org/714168#c2, NM_UNMANAGED is properly set for the affected interfaces. This should be fixed in the ebuild. In the v1.38.0 NEWS file I see
> * Veth devices with name "eth*" are now managed by default via the
> udev rule. This is to support managing the network in LXD containers.
Does this resolve the issue?

/lib/udev/rules.d/85-nm-unmanaged.rules contains the lines # Virtual Ethernet device pair. Often used to communicate with a peer interface # in another net namespace and managed by libvirt, Docker or the like. ENV{ID_NET_DRIVER}=="veth", ENV{NM_UNMANAGED}="1" But on my system running eudev, the ID_NET_DRIVER variable is not set. Here's the udevadm output for a veth device: # udevadm info /sys/devices/virtual/net/veth9f54ce0a calling: info P: /devices/virtual/net/veth9f54ce0a E: DEVPATH=/devices/virtual/net/veth9f54ce0a E: ID_MM_CANDIDATE=1 E: IFINDEX=12 E: INTERFACE=veth9f54ce0a E: SUBSYSTEM=net E: USEC_INITIALIZED=11188430 Reproducible: Always Steps to Reproduce: 1. Install networkmanager. 2. Install docker or lxd and create a container. 3. Check to see if the virtual ethernet interfaces are managed. Actual Results: In practice, the interfaces are not recognized by eudev using the default rules and NM_UNMANAGED is not set. Expected Results: The interfaces should be recognized as virtual ethernet interfaces and NM_UNMANAGED set accordingly.
