For ethernet devices, a device is usually "unavailable" because it has no carrier.As a matter of fact, when no udev rules for NM_UNMANAGED, the device is in the disconnected state.

Regarding the last mystery above : I guess the trace is no sufficient for you to explain anything ? Again, what's weird is that the host is a VMWare VM with eth1 device 'connected', so I don't see any reason why it would have no carrier...
Hi,
sorry for the late reply.
You say "udev rules for NM_UNMANAGED" but there is:
(eth1): unmanaged: flags set to [user-udev,!sleeping,!l
the "user-udev" tells you there is a udev rule for that.
The confusing part here is the double negative with "UNmanaged".
"!sleeping" here means that it's not unmanage due to sleeping
"user-udev" here means, it's unmanaged due to user-udev.
See also, /usr/lib/udev/rules.d/85-nm-unmanaged.rules which has:
# VMWare host networking. Out-of-tree driver that looks like an ordinary
# Ethernet. No parent device (lives in /virtual/), no support for
# ethtool to identify the driver. They have their own MAC prefix that
# can not be changed.
ATTR{address}=="00:50:56:*", ENV{INTERFACE}=="vmnet[0-9]*", ENV{NM_UNMANAGED}="1"
(note the MAC address). Hm, I am a bit suprised, because the interface name doesn't seem
to be ENV{INTERFACE}=="vmnet[0-9]*". Dunno what's going on there.
What gives
udevadm test /sys/class/net/eth1
?
It would be interesting to see the entire logfile.
Best,
Thomas
