NetworkManager problema com servidores dns

Question

Eu tenho duas placas de rede, uma é a bordo e a outra é uma placa PCI adicionada. Eu também criei uma interface de ponte para uso em minhas máquinas virtuais KVM, então meu desktop (host) usa a interface enp3s0 e as VMs (guests) usam a interface enp4s3 através de um ponte que eu criei chamado VM-NetBridge. Aqui está o comando ip:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: enp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 30:5a:3a:0b:43:1b brd ff:ff:ff:ff:ff:ff
    inet 192.168.0.35/24 brd 192.168.0.255 scope global enp3s0
       valid_lft forever preferred_lft forever
    inet6 fe80::325a:3aff:fe0b:431b/64 scope link 
       valid_lft forever preferred_lft forever
3: enp4s6: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master VM-NetBridge state UNKNOWN group default qlen 1000
    link/ether 00:e0:7d:75:cd:d7 brd ff:ff:ff:ff:ff:ff
    inet6 fe80::2e0:7dff:fe75:cdd7/64 scope link

    inet 192.168.0.110/24 brd 192.168.0.255 scope global VM-NetBridge
       valid_lft forever preferred_lft forever
    inet6 fe80::2e0:7dff:fe75:cdd7/64 scope link 
       valid_lft forever preferred_lft forever

    link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff
    inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0
       valid_lft forever preferred_lft forever
6: virbr0-nic: <BROADCAST,MULTICAST> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000
    link/ether 52:54:00:82:71:44 brd ff:ff:ff:ff:ff:ff
7: virbr1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default qlen 1000
    link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff
    inet 192.168.100.1/24 brd 192.168.100.255 scope global virbr1
       valid_lft forever preferred_lft forever
8: virbr1-nic: <BROADCAST,MULTICAST> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000
    link/ether 52:54:00:55:a9:3a brd ff:ff:ff:ff:ff:ff
9: vnet0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master VM-NetBridge state UNKNOWN group default qlen 1000
    link/ether fe:54:00:bf:f8:70 brd ff:ff:ff:ff:ff:ff

Agora, estou tendo um problema com os servidores de nomes: toda vez que eu inicializo tenho que deletar um arquivo e atualizar o resolvconf. Eu fiz um script com isso:

#! /bin/zsh

if [ -f /run/resolvconf/interface/NetworkManager ]; then
    sudo rm /run/resolvconf/interface/NetworkManager
    sudo resolvconf -u
fi

Isso resolve o problema, mas não sei por que esse arquivo ( NetworkManager ) é criado automaticamente em /run/resolvconf/interface/ e como evitar isso.

Eu também não consigo configurar a segunda placa de rede, porque ela me mostra que ela não é gerenciada.
