vagrant creates two interfaces when I ask for a bridged adapter

[Michal Koziel]

Host: Windows8, Guest: CentOS6.6, Vagrant  1.7.2, VirtualBox 4.3.28

vagrant creates two interfaces when I ask for a bridged adapter in the Vagrantfile like this:

config.vm.network "public_network", bridge: "Realtek PCIe GBE Family Controller", ip: "192.168.1.4", netmask: "255.255.255.0", :use_dhcp_assigned_default_route => false

The two interfaces (eth1 and eth2) gets the same settings, except of the MAC address.

I have deleted /etc/sysconfig/network-scripts/ifcfg-eth1 and /etc/sysconfig/network-scripts/ifcfg-eth2

I have also removed /etc/udev/rules.d/70-persistent-net.rules

And added

ln -sf /dev/null /lib/udev/rules.d/75-persistent-net-generator.rules

Then reloaded VM, but th interfaces are again added. 

Is there anything I'm doing wrong? How do I fix this so only one bridged interface is added?

Sure:

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|

  config.vm.box = "Empty"

  config.vm.provider "virtualbox" do |vb|

    vb.gui = true

    vb.customize ["modifyvm", :id, "--vram", "128"]

    vb.customize ["modifyvm", :id, "--hwvirtex", "on"] 

    vb.customize ["modifyvm", :id, "--clipboard", "bidirectional"]

    vb.customize ["modifyvm", :id, "--usb", "on", "--usbehci", "on"]

    #to get usb device info, connect usb device and run on host: $ vboxmanage list usbhost

    vb.customize ['usbfilter', 'add', '0', '--target', :id, '--name', 'Altera', '--action', 'hold', '--active', 'yes', '--vendorid', '0x09fb']

    vb.customize ["modifyvm", :id, "--memory", 4096]

    vb.customize ["modifyvm", :id, "--cpus", 4]

    config.vm.network "public_network", bridge: "en1:Realtek PCIe GBE Family Controller", ip: "192.168.1.4", netmask: "255.255.255.0", :use_dhcp_assigned_default_route => false

    config.vm.synced_folder "e://Dropbox//Linux", "//media//sf_linux"

  end

end

Ok

the problem is where the config.vm is

it's insise the virtualbox block

Take it out, since vagrant read the file multiple times ..

VAGRANTFILE_API_VERSION = "2"
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
config.vm.box = "Empty"
config.vm.provider "virtualbox" do |vb|
vb.gui = true
vb.customize ["modifyvm", :id, "--vram", "128"]
vb.customize ["modifyvm", :id, "--hwvirtex", "on"]
vb.customize ["modifyvm", :id, "--clipboard", "bidirectional"]
vb.customize ["modifyvm", :id, "--usb", "on", "--usbehci", "on"]
#to get usb device info, connect usb device and run on host: $
vboxmanage list usbhost
vb.customize ['usbfilter', 'add', '0', '--target', :id, '--name',
'Altera', '--action', 'hold', '--active', 'yes', '--vendorid',
'0x09fb']
vb.customize ["modifyvm", :id, "--memory", 4096]
vb.customize ["modifyvm", :id, "--cpus", 4]

end

config.vm.network "public_network", bridge: "en1:Realtek PCIe GBE
