$ vagrant up [ruby-2.1.5@rails-41]
checking for ansible-playbook... yes
Bringing machine 'imobi' up with 'virtualbox' provider...
==> imobi: Checking if box 'ubuntu/trusty64' is up to date...
==> imobi: Clearing any previously set network interfaces...
A host only network interface you're attempting to configure via DHCP
already has a conflicting host only adapter with DHCP enabled. The
DHCP on this adapter is incompatible with the DHCP settings. Two
host only network interfaces are not allowed to overlap, and each
host only network interface can have only one DHCP server. Please
reconfigure your host only network or remove the virtual machine
using the other host only network.
Can you try it once again please? There's some issues with DHCP network configuration in vagrant/VirtualBox, so I've decided to switch to static IP network.
