You shouldn't have "dns-search opendns.com" here.

Do you have a "dhcp=" or dns=" line in
"/etc/NetworkManager/NetworkManager.conf"?

Is dnsmasq running?

What;s the output of "dig" (just "dig"?

If I were you, I'd comment out all the eth0-related lines in
"/etc/network/interfaces" and set up NM via its GUI.

Or I'd create the following file and chown+chmod it.

# vi /etc/NetworkManager/system-connections/eth0
[connection]
autoconnect=true
id=eth0
type=802-3-ethernet
uuid=<generate_with_'uuidgen'>
[ipv4]
ignore-auto-dns=true
dns=208.67.222.222;208.67.220.220;
method=auto
[ipv6]
method=auto

# chown root:root /etc/NetworkManager/system-connections/eth0

# chmod 0600 /etc/NetworkManager/system-connections/eth0

There's no resolvconf process. "resolvconf -u" is triggered by the
hooks of the various programs that have them.
