vagrant up command giving error and eth1 not showing a resolvable ip address

I am new to VMs, but have been using vagrant to run a Centos VM on Ubuntu 14.04. All of a sudden vagrant up command is giving this error:

The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!

ARPCHECK=no /sbin/ifup eth1 2> /dev/null

Stdout from the command:

Stderr from the command:

I am able to vagrant ssh to VM but eth1 is no longer giving a resolvable ip (i.e. it does not give inet addr paramater. How to resolve this?

P.S. https://unix.stackexchange.com/questions/188413/not-able-to-resolve-ip-address-for-eth1-in-vagrant-vm

I have tried some tinkering with eth1 as suggested in above link but to non avail. PLz help. Thanks.

It turns out that eth2 is the adapter to connect the Virtual-box directly to the outside Internet, so commenting out

config.vm.network :public_network

from the VagrantFile stopped the public network interfaces being loaded and so solved the issue.

This seems to be happen with bootup network configurations.

Although it failed to bring-up the network interface, you should be able to ssh into the box. To remove persistent network interfaces execute following commands in vagrant box folder.

vagrant ssh
sudo rm /etc/udev/rules.d/70-persistent-net.rules
exit
vagrant reload
