By default, LXC sets up dnsmasq to issue a lease expiration of 1 hour. Thus if you suspend and resume your laptop after more than an hour has passed, your containers will lose their hostnames and can no longer communicate with one another by host name, as dnsmasq has forgotten about them.
To fix the issue for Ubuntu 14.04, edit /etc/default/lxc-net. Find the line:
LXC_DHCP_RANGE="10.0.3.2,10.0.3.254"
and change it to
LXC_DHCP_RANGE="10.0.3.2,10.0.3.254,72h"

| Install Ubuntu 14.04 Server 64-bit into the VM of yor choice. Parallels works best on a Mac. Virtual Box also works, but is slower | |
| Log in to your VM and run our LXC-host setup script. Thsi first run will take a while: | |
| wget https://raw.github.com/turbosquid/lxc-host-setup/master/host-setup.sh | |
| bash host-setup.sh | |
| We assume you have a development directory on your macbook that contains subdirectories for each project. Use an NFS share on your host to map this directory in to your VM. Follow the instructions in this [gist](https://gist.github.com/mowings/9782264). | |
| You should now be able to log in to your VM and do a `vagrant up` in anyproject subdirectory to bring up a container for the project. IMPORTANT: If you have just upgraded your vm, delete the old `.vagrant` directory in your project! Otherwise vagrant up will not provision the container. If you forget, just do a `vagrant provision` after your vagrant up. |
