link /etc/dhcp3 to make vCloud Guest Customization work

[StefanScherer]

Hi @frapposelli,

I have read your latest article of using Docker in vCenter and also vCloud. I stuck with Ubuntu 14.04 in our vCloud some time ago. But your article was interesting enough for me to look deeper what's wrong with the Ubuntu 14.04 boxes.

I tried my ubuntu1404 box, based on the box-cutter/ubuntu-vm Repo, but after powering on, the SSH connection does not work. So I tried your gosddc/trusty64 box, but I run into the same problem. No SSH and so no provisioning etc.

I had to log into these two boxes with vCloud Director and found out that the network cards had problems. The /etc/hostname already has the correct name, as well as the /etc/hosts table is already updated. But no network connection. After rebooting the guest, SSH connection works.

After some googling, I found this vmware community article.

So I came up with a fix for my ubuntu1404 boxes with this commit in my branch. I just followed the tip that a symbolic link /etc/dhcp3 should exist and point to /etc/dhcp.

And yes, my ubuntu1404 box is built correctly and was testable with my basebox-slave serverspec tests.

Seems to do the trick.

So it might be helpful for others that the gosddc/trusty* boxes should also have this patch.

Do you have another patch/update for the vCloud that fixes it inside the Guest Customization scripts?

I don't know our exact vCloud Director version.

I have a running Dock your Container example running in our vCloud. But I had another issue with missing entries in /etc/resolv.conf. I then added a shell provision script that helps me to make DNS lookup work. Any hints what's wrong?

I will look into that shortly, the /etc/resolv.conf problem is an old one, I think it's due to an upstream bug in vCD.
