[systemd-devel] Networkd fails to activate the device on boot

[Thomas Bächler]

Hello Tom,

I am using systemd 215-4 from Arch Linux.

I have the following configuration files in /etc/systemd/network:

# 01-lan.network
[Match]
Name=enp3s0

[Network]
Address=10.23.42.4/26
Gateway=10.23.42.3

# 01-qemu.netdev
[NetDev]
MACAddress=1a:de:ad:be:ef:01
Name=qemu
Kind=tap

# 01-qemu.network
[Match]
Name=qemu

[Network]
Address=10.23.42.129/26

I have two problems with this setup:

1) The enp3s0 interface does not activate on boot. I need to restart
networkd manually to make it work.

2) The qemu interface does not have the correct MAC address. It gains a
seemingly random address that is inconsistent across reboots.

Here is an excerpt from the journal:

Any ideas?
