Why is Vagrant making up an incorrect subnet when it's just supposed to port-forward?

vagrant, virtualbox

Solution

Ssh into the machine

Delete the file /etc/udev/rules.d/70-persistent-net.rules

Exit the machine

Do a "vagrant reload"

I think that does the trick =]

Problem

Host is Windows 8.1; provider is VirtualBox 4.3.4; Vagrant version is 1.3.5. Host has just a single NIC, wired, with IP 192.168.1.100. Vagrantfiles reads: ``` config.vm.box = "precise64" config.vm.box_url = "http://cloud-images.ubuntu.com/vagrant/precise/current/precise-server-cloudimg-amd64-vagrant-disk1.box" config.vm.network :forwarded_port, guest: 80, host: 8080 config.vm.provision :puppet do |puppet| puppet.manifests_path = "puppet/manifests" puppet.module_path = "puppet/modules" puppet.manifest_file = "init.pp" puppet.options="--verbose --debug" ``` However, following `vagrant up`, the VM gets a completely wrong IP address. `ifconfig` for the guest reads: ``` vagrant@vagrant-ubuntu-precise-64:~$ ifconfig eth0 Link encap:Ethernet HWaddr 08:00:27:1a:b6:5e inet addr:10.0.2.15 Bcast:10.0.2.255 Mask:255.255.25 inet6 addr: fe80::a00:27ff:fe1a:b65e/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:356 errors:0 dropped:0 overruns:0 frame:0 TX packets:239 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:38937 (38.9 KB) TX bytes:33157 (33.1 KB) ``` Why is Vagrant totally ignoring the port forwarding setting on the vagrantfile? IP address should be `192.168.1.x`and instead I get this random `10.0.2.15`. Any ideas? Edit: Host can't even ping `10.0.2.15`. No response, even when the VM is up. Something is very broken. Edit 2: Now I'm getting `/sbin/ip addr flush dev eth1 2> /dev/null` on 2 different systems. Argh.
