#virtualbox

When you create a virtual hard disk in VirtualBox or VMware, you specify a maximum disk size. If you want more space on your virtual machine’s hard disk later, you’ll have to enlarge the virtual hard disk and partition.

This describes how to update Vagrant’s lucid64.box base box to the latest Guest Additions for VirtualBox 4.0.4. The only wrinkle was that the base box did not have the ppa:debfx/virtualbox repository configured.

"Ok, that Ubuntu issue is a known problem. It saves the assignment of MAC ethX using an udev rule. Have a look at /etc/udev/rules.d and you will find a file 70-persistent-net.rules there. You can savely remove this file. This file is auto-generated by /lib/udev/rules.d/75-persistent-net-generator.rules. You can remove that file as well. From now on, the guest will no longer store the assignment between the MAC and ethX interface."

"When I'm developing, I try to continuously deploy to a realistic environment as often as possible. This means a Debian server running a stack as close to production as I can get. Of course, I don't deploy to the actual production servers (a lesson I've learnt many times over), so I virtualise a Debian box and clone package set from the production server. Combined with bridged networking and a quick hosts file change, and I've got a production-equivalent server always available at server.local."
