Continuing on with our self-learning to become a System Administrator, this article of Building the Ultimate VirtualBox Lab series we are focusing on how to install.Raspbian x. 86 on Virtual. Box on a Windows PCaoakley. Support family coding workshops in Gloucestershire. Oracle's Virtual. Box is a user- friendly way of installing a virtual machine on a PC. In short, you can run a computer inside your computer - for example, the Raspberry Pi desktop inside your Microsoft Windows desktop. There are lots of other products that also do this, but Virutal. Status: Guest OSes. The following table gives an overview of how well VirtualBox operating systems work in its virtual machines. Rows marked with an asterisk. Box is one of the easiest to use. I do usually pack at least one real Pi, but having it all on my laptop is a huge convenience. It can be done - you might have Virtual. Box take control of a USB port and use Ryanteck's RTk. GPIO for example.. You can also do this on a Mac or Linux PC; if you're using one of those, the installation of Virtual. Box may be different, but the setup should be mostly the same. If you don't have this, or don't know how to check, don't worry about it. If you don't intend to do much else with your PC, you could get away with as little as 2. We provide pre-built images for several open-source operating systems. Please note that: Every image contains the latest software as of the day the image was built. Oracle's VirtualBox is a user-friendly way of installing a virtual machine on a PC. In short, you can run a computer inside your computer - for example, the Raspberry. Download GNS3 for free. A graphical network simulator to design and configure virtual networks. GNS3 is a graphical network simulator that allows you to design. GB RAM. You don't need to download the Extension Pack nor the Software Development Kit. We'll install the Guest Extension Pack another way, later. Alternatively you may find it in your browser's Download area and there may be an . Keep it short. I suggest rpi or raspberrypi. You now need to attach the Raspbian x. ISO file to the imaginary CD- ROM drive. You will shortly see . You should select the Raspbian x. ISO file that you downloaded earlier, and click the Start button. After a moment, you'll see a list of languages; select yours, then click Continue. Give it a couple of minutes. For convenience, I suggest you leave it at . It'll show the one and only virtual hard drive; click Continue again. You should now see . This is the bit that can take a while. Assuming you selected . Otherwise you can go and eat some grits, whatever they are. It tells you a load of guff about removing the CD- ROM, but you don't need to worry about that, just click Continue. We need to change one setting - simple! Then click OK. Thankfully you only need to do this once; it should be remembered for all future times. You'll see the Virutal. Box startup screen, the swirly GRUB screen, then the Raspbian desktop will start to load. But it's a bit smalll and cramped - 6. Also, you can't copy and paste between the virtual Pi and the real Windows desktop. Let's sort out those niggles. However you can make it even better by installing Virtual. Box Guest Extensions to the virtual Raspberry Pi, which lets the virtual Pi know that it's not real and that it exists inside another computer. This will allow you to resize the desktop, and enable copy & paste. Press Enter at the end of each line. If only you could copy and paste it, rather than having to type it in.. It'll take a little while to download and install the extensions. Neat, isn't it?). The virtual Pi will reboot after the shutdown command. You can also set a defined size, such as 1. Virtual. Box's View - Virtual Screen 1 - Resize to (whatever you fancy). You may need to click a running program for the virtual Pi to notice the change and resize the task bar. Once you have the virtualbox- guest extensions installed, then you can use Virtual. Box's Devices - Shared Clipboard - Bidirectional menu to enable copy and paste between the virtual Pi and your real PC. You'll still need Guest Extensions installed, though. You'll need to add the pi user to the vboxsf group as per Peter WA Wood's instructions (thanks, Peter - Peter WA Wood's website is full of various interesting Linux, BSD, *nix and Mac. OS articles, take a look). Go to the terminal on your virtual Pi and enter. G vboxsf pi. You can then share folders from Virtual Box using Settings - Shared Folders and click on the folder add icon. Folders will appear under /media with the prefix: sf? Perhaps.). Minecraft and Wolfram are, I suspect, licencing issues. The GPIO ports are a physical vs. So you can't copy over binary executables from a real Raspberry Pi and expect them to work - they won't. However, source code and scripts such as Python, Scratch and Bash will work, as will anything that you install using apt from the repository (because some very nice volunteers have recompiled almost everything in the Raspbian repository for both ARM and Intel architecture). You can place an . Also there's no point in a . Alternatively you can use sudo raspi- config from the command line. Reboot when done. To do this, from Virtual. Box, select Settings, Network, Advanced, Port Forwarding and click the Add icon. Beware that Microsoft Windows may already be running an SSH server on port 2. Guest Port) from the virtual Pi, to a different port such as 2. Host Port). You don't need to worry about the Host IP or Guest IP; leave those fields blank and Virtual. Box will assume sensible defaults. If you need to SSH from outside your Microsoft Windows machine, you may need to check your firewall. You can find your virtual Pi's IP address by hovering over the network icon at the top- right of the Raspbian desktop, or you can issue hostname - i from the command line. Outbound routing (from virtual machine to real machine and real world) is configured automatically; inbound routing (from real world to virtual machine) is not, hence you have to set port forwarding. For example if your virtual Pi is on 1. Microsoft Windows desktop using that IP; you have to use port forwarding from localhost. There probably is a way of doing inbound routing in Virtual. Box, but to be honest that's an advanced topic for which I'd expect you to be using a more hardcore virtualisation host. It probably wouldn't be too hard to have multiple virtual Pis all chatting away to each other on Virtual. Box's 1. 0. To turn it off, either issue the sudo shutdown - h now command from SSH, or right- click the . Another top headless tip is that you can boot without the desktop by doing sudo raspi- config, selecting . We run entirely on donations, we don't claim tax relief nor taxpayer- funded grants, and in addition to running four workshops for 6. GPIO electronics kits. All cards are accepted and you don't need a Pay. Install Oracle Solaris 1. Oracle VM Virtual. Box. What You See Is What You Get Element. Lab: Install Oracle Solaris 1. Oracle VM Virtual. Box. Hands- On Labs Of the System Admin and Developer Community of OTNby Jeff Mc. Meekin. In this lab, you will learn how to install the Oracle Solaris 1. Image for Oracle VM Virtual. Box—the easiest way to get up and running with Oracle Solaris 1. Published April 2. Prerequisites. This lab is the first is a series of labs for Oracle Solaris 1. All of the labs in the series have these prerequisites in common: Operating system: Windows, Mac OS X, Linux, or Oracle Solaris on x. Memory: 2 GB of RAMBefore starting the lab, ensure you have installed the following: Also, you must enable hardware virtualization support in the BIOS. Screens might look slightly different on a PC.)Figure 1. Selecting the appliance to import. Browse to the location where you downloaded the Oracle Solaris 1. VM and select it. Appliance settings screen. Scroll down to check how much memory is allocated to the image. Oracle Solaris 1. GB of memory. Figure 3. Checking the amount of allocated memory. Click the Import button. Exercise 3: Start the Oracle Solaris 1. VMIn this exercise, we will run Oracle Solaris 1. Select the Oracle Solaris 1. VM and click the green arrow labeled Start. Figure 4. Starting the VMOn first boot, the System Configuration Tool runs, prompting you to enter system information providing an explanation of what is to follow. Note that during installation, you have to actively switch between the VM and your host OS. Oracle VM Virtual. Box will open a window to explain this. First screen of the System Configuration Tool. The next screen will prompt you for system name. The third screen will prompt for networking settings. Make sure you enter user account information as well as the root password. Screen for entering user account and password information. Next, there will be two screens to enable the Oracle Configuration Manager, that is, 'phone home' capability. Summary screen. Press F2 to apply the specified configuration, and then Oracle Solaris will complete the configuration/boot process. Log in to Oracle Solaris using the user account you set up in Step 8 above. For this example, we created the user demo during the configuration step, so we now log into that account. Figure 8. Login screen. After logging in, you should see the blank background of the user's desktop. Bring up a terminal window by clicking the icon that looks like a computer screen (located on the left side of the top bar of the Oracle VM Virtual. Box window). Figure 9. Opening a terminal window. To get started, investigate the Oracle VM Virtual. Box package by running the command pkginfo - l SUNWvboxguest in the terminal window. Figure 1. 0. Investigating the Oracle VM Virtual. Box package. The Oracle Solaris guest additions package creates tighter integration between the host OS and Oracle Solaris. For example, you can cut and paste text between the two operating systems. You can also put Oracle Solaris into full- screen mode. Do this now by selecting Machine > Switch to Fullscreen. Exiting full- screen mode is most easily accomplished by moving your mouse cursor to the bottom middle of the screen, which will cause a menu to appear. Next, enter the following command. This will print out data about all the pools and subpools created. Listing data about all the pools and subpools. If you regularly use sudo(1), you can type in a command such as the following and enter the password of the demo account. Hence, it can operate with root privileges. Exercise 4: Take a Snapshot. There are two ways to take a snapshot of your environment. This includes a snapshot of the local file system. To take a snapshot, from the Virtual. Box menu, select Machine > Take Snapshot. Give the snapshot a name and optional description: Figure 1. Creating a snapshot. The other approach is using the capability of ZFS. There are two ways to do this: one for system administrators and one for users. For System Administrators (SAs)To create a snapshot (called a boot environment . In the unlikely situation there is a problem from this action, the SA can reboot to safety- net- be to get back to a known working state. When updating packages, for example, installing the monthly Support Repository Update, a boot environment is typically automatically created and the patches will be applied to that BE, not to the running system. Over time as changes are made, and new blocks are modified, added, or deleted, the snapshot grows. Time Slider can be accessed from the desktop through System- > Administration- > Time Slider. Wrap Up. That's it for this very brief introduction. Now you have an environment in which you can begin to learn about all the great features in Oracle Solaris 1. And with the snapshot features mentioned above, you never have to worry about messing anything up, because you can always roll back to a prior known good state. When you are ready to halt the VM, go to the upper left corner of the display and click System.
