[Solved] Failing to start dhcpcd@eth0 inside libvirt-lxc vm

Question

What the subject says.
I was thinking that this could be some systemd 197 related problem. I've downgraded
to 196 and the problem remains. I have the latest version of all packages (linux, libvirt, etc.)
See the log below, please. Note that the there is a eth0 interface.
[arch@gitolite ~]$ ip link
12: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT qlen 1000

Can anyone help, please?

Answer 1

I'm trying to get this running without using systemd.
I restart the domain, and do
# ip link set eth0 up
# ip link show eth0
14: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT qlen 1000
link/ether 02:00:00:00:00:17 brd ff:ff:ff:ff:ff:ff
# dhcpcd eth0
dhcpcd[44]: version 5.6.4 starting
dhcpcd[44]: eth0: if_init: Read-only file system
dhcpcd[44]: eth0: interface not found or invalid
What does this mean? I googled for it, but didn'g find anything
In the guest, the only filesystem marked as read-only is /sys.
Any idea?
