    Video tutorial on how to How to Use Oracle Virtual Box by Cisco and NET+ instructor Mark Jacob. By far easier than re configuring an actual machine, you can make the virtual machine the way you want it, save that snapshot, and get back to it if you want. You can save the snapshot, clone it and then move on with the clone returning. You have lots of variety that you can do.

    How to Use Oracle Virtual Box

    Video Transcript:
    I wanted to share with you a free download, which is Oracle’s Virtual Box Solution. If you are a person who’s, perhaps, planning on taking a CompTIA Network+ Certification class here at Interface, it would do you well to spend a little time in advance getting familiar with it.

    But even if you’re not, if you’ve never been associated with Virtual Box, I just want to take a few minutes, and show you some of these things you can do with it.

    I have on screen, already, a pre‑loaded instance of Virtual Box with some Virtual Machines already built. If you take a moment to look, you’ll see this little icon up here on the top left. That is a 64‑bit version of Windows Server 2008.

    The one below that, the Gateway Box, is also Server 2008.

    Then I have a Client machine which is XP.

    003-Client-XP-how-to-use-oracle-virtual-box

    This one here is remote; it didn’t exist when I first started which pretty much describes all of these.

    004-Client-XP-how-to-use-oracle-virtual-box

    None of these existed before I created them, but the Remote Box is actually a clone of the Client machine.

    Once you’ve created a box, machine, PC, whatever you want to call it, inside Virtual Box. If you want to save a copy of that and use it for other purposes without ruining the first one, you can create a clone of it.

    You also have the ability as you’ll notice. For instance, I have router highlighted.

    005-Client-XP-how-to-use-oracle-virtual-box

    That one is a Linux machine, Ubuntu and so is this one here, the lab machine.

    But you’ll notice here, on the right screen, that I have snapshots. I have this button up here that says “snapshots”. That’s another cool feature of Virtual Box.

    006-Client-XP-how-to-use-oracle-virtual-box

    Let’s say you build a home lab and you can have multiple servers, clients, whatever you want. You can configure DNS, you can configure DHCP server, and you can set up these machines to all talk to each other. You can even set them up if you need them to access the actual Internet. You can do that.

    But you can build a lab environment; run some test commands on it, and then let’s say you configure some additional features, you can snapshot that and then they say you continue the lab, do more things. I don’t like what I did. I want to go back to where I was before. You can revert to a previously configured snapshot.

    For instance, if I click on this configuration, you’ll notice I can delete the snapshot.

    007-Client-XP-how-to-use-oracle-virtual-box

    It’s great out right now, because I’m active but I can restore that snapshot, put the machine back to the way it was.

    By far easier than re‑configuring an actual machine, you can make the virtual machine the way you want it, save that snapshot, and get back to it if you want. You can save the snapshot, clone it and then move on with the clone returning. You have lots of variety that you can do.

    As I mentioned, if you were planning on taking the CompTIA Network + class here at Interface, become familiar with this. Download it and build some Virtual Machines in there, because it is used in the lab environment. If you have some experience with it, there’ll be less of a learning curb for that, because it’s a network class, not a Virtual Box class. Do yourself a favor and get familiar with this virtualization solution.

    Until next time…
