How to tell NM to ignore some interfaces

[Jetchko Jekov <jetchko jekov gmail com>]

Hello,

I am pretty sure that this question was raised several times already on this list as I found some references when searching. But somehow none of proposed settings work for me.

In general, I want to tell NM to ignore all virtual interfaces which are not explicitly created with it. For example interfaces created by libvirt, virtual box, docker (that includes bridges, veth pairs, tun/tap interfaces and so on) . These are not in control of NM and I am not sure why NM insist on reporting status and/or  controlling them.

Currently I am trying tell NM to ignore tap interface which is my end of VPN tunnel without success at all. It insist to run dhclient on this interface breaking my network setup.

after many iterations my current config (as parsed by NM itself) is:

nm_config_data_log(): CONFIG: [main]

nm_config_data_log(): CONFIG:   plugins=keyfile,ifupdown,ifcfg-rh,ibft

nm_config_data_log(): CONFIG:   dns=dnsmasq

nm_config_data_log(): CONFIG:   no-auto-default=*

nm_config_data_log(): CONFIG:   ignore-carrier=*

nm_config_data_log(): CONFIG:

nm_config_data_log(): CONFIG: [ifupdown]

nm_config_data_log(): CONFIG:   managed=false

nm_config_data_log(): CONFIG:

nm_config_data_log(): CONFIG: [logging]

nm_config_data_log(): CONFIG:   level=DEBUG

nm_config_data_log(): CONFIG:

nm_config_data_log(): CONFIG: [connectivity]

nm_config_data_log(): CONFIG:   uri=http://fedoraproject.org/static/hotspot.txt

nm_config_data_log(): CONFIG:   response=OK

nm_config_data_log(): CONFIG:   interval=300

nm_config_data_log(): CONFIG:

nm_config_data_log(): CONFIG: [keyfile]

nm_config_data_log(): CONFIG:   unmanaged-devices=interface-name:~virbr?;interface-name:~vboxnet?;interface-name:~docker?;interface-name:tap?;interface-name:~tap?;type:tap

and the result is:

$ nmcli d

DEVICE             TYPE      STATE         CONNECTION 

virbr0             bridge    connected     virbr0     

em1                ethernet  connected     em1        

tap0               tap       connected     tap0       

wlo1               wifi      connected     NOSI       

lo                 loopback  unmanaged     --         

virbr0-nic         tap       unmanaged     --         

ps ax | grep dhclient | grep tap

26168 ?        S      0:00 /sbin/dhclient -d -q -sf /usr/libexec/nm-dhcp-helper -pf /var/run/dhclient-tap0.pid -lf /var/lib/NetworkManager/dhclient-e9f78bcd-46f6-4092-9246-a6139ed0e713-tap0.lease -cf /var/lib/NetworkManager/dhclient-tap0.conf tap0

and I dont have ifcfg-tap0 file in /etc/sysconfig/network-scripts

$ NetworkManager --version

1.0.6-8.fc22

So in short, How can I tell NM to ignore tap0 (and virbr0 for that manner).

Any help is highly appreciated.

Best regards,

Jeka
