This post provides a basic introduction to the VirtualBox CLI (command-line interface) tool, vboxmanage. This post does not attempt to replace the comprehensive documentation; rather, its purpose is to help users who are new to vboxmanage (such as myself, having recently adopted VirtualBox for my Vagrant environments) get somewhat up to speed as quickly and as painlessly as possible.
Let’s start with some basic operations. Here are a few to get you started:
To list all the registered VMs, simply run vboxmanage list vms. Note that if you are using Vagrant with VirtualBox, this command will also show VirtualBox VMs that have been instantiated by Vagrant. Similarly, if you are using Docker Machine with VirtualBox, this command will show you VMs created by Docker Machine.
To list all the running VMs, use vboxmanage list runningvms.
To start a VM, run vboxmanage startvm <name or UUID>. You can optionally specify a --type parameter to control how the VM is started. Using --type gui will show it via the host GUI; using --type headless means you’ll need to interact over the network (typically via SSH). To emulate Vagrant/Docker Machine-like behavior, you’d use --type headless.
Once a VM is Continue reading

Was there something that you didn’t quite get and needed an explanation? Congratulations. You’re in a quiet group of people that ask questions for knowledge. More and more, we are seeing questions becoming a vehicle for more than just knowledge acquisition. If you want to learn how to ask a proper question at a conference, read on.
I know it goes without saying, but if you’re going to raise your hand at a conference to ask a question, you should actually have a question in mind. Some people grab a microphone without thinking through what they’re going to say. This leads to stammering and broken thoughts that usually culminate in a random question mark here or there. This makes it difficult for the speaker to figure out what you’re trying to ask.
If you’re going to raise your hand, jot some notes down first. Bullet points help as does making a note or two. This is especially true if the speaker is answering questions before yours. If they answer part of your Continue reading
