You can edit Vagrantfile file in any standard text editor or via VIM:
$ cd /Web
$ vim Vagrantfile
Locate a line that starts with:
(Note that the IP address will likely be different on your machine)
config.vm.network "private_network", ip: "192.168.100.1"
and append ":auto_config => false" so it looks like:
config.vm.network "private_network", ip: "192.168.100.1", :auto_config => false
(might be able to just vagrant halt... then a vagrant reload --provision later, but destroying vagrant has worked thus far)
$ vagrant destroy
$ cd ./WallaWeb
$ vim Vagrantfile
locate (IP address may be different):
config.vm.network "private_network", ip: "192.168.100.1",
and append ":adapter => 2" so it looks like:
config.vm.network "private_network", ip: "192.168.100.1", :adapter => 2
$ vagrant up
Note that this will probably result in an error about the ethernet devices... but the vagrant box should spin up.
$ vagrant ssh
$ vagrant ssh
$ sudo sed -i 's/eth1/eth2/' /etc/sysconfig/network-scripts/ifcfg-eth1
$ sudo /sbin/ifup eth1
$ vagrant up
