![]() ![]() Likewise, if you’re deploying infrastructure nodes (e.g., Kubernetes workers) that will then run workloads of their own, the extra speed of a fixed-size disk may be desirable, if you have the SSD space to spare.įinally, pick the size of your virtual hard disk. If you plan on building a lot of containers, you may find the extra speed useful and worth the mass storage cost. Fixed-size disks consume all their allocated space immediately, but run a little faster. Dynamic disks grow as they get filled up, so consume less of your mass storage. On the next screen, determine if you want to create a dynamically-sized or fixed virtual hard disk file. ![]() On the next screen, select the radio button to create a virtual hard disk file.Īnd select the radio button to use VDI format for the virtual disk. These two servers are sufficiently resourced to host, for example, a Mirantis Kubernetes Engine manager and worker node, which is enough for basic evaluation and even laboratory use of this powerful Kubernetes/Swarm platform. For what it may be worth, on a 32GB Windows laptop, you have enough room to run two virtual servers with 12GB RAM each (12GB = 12228MB, as shown below in the context of VirtualBox's memory allocator), while also leaving enough room for Windows and basic applications. Since we’re building servers for hosting (for example) Kubernetes manager or worker nodes, we usually want to set RAM to be as large as practical - understanding that this needs to be a compromise based on other resource demands on the host (including the presence of other running virtual machines). You’ll use this initial VM image to create new VMs as you need them (a process called “cloning”).Ĭlick Next, and assign a reasonable amount of RAM to your VM. Give your machine a generic name that identifies it by operating system and version. Select Linux and Ubuntu (64-bit) from the popdowns. Start VirtualBox, and click on the top menu: Machine>New (or press CTRL-N).

I’ll also write about using it effectively in another article. I’d also advise installing VirtualBox Guest Additions on Ubuntu or whatever guest system you’re using in your VM to get a better and smoother experience. I hope you were able to use one of these methods to install VirtualBox. That’s not an entirely bad thing, because you may want to keep them safe and use them later or in some other system. Note that this will not remove the virtual machines and the files associated with the operating systems you installed using VirtualBox. You just have to find it in the list of installed applications and click the Remove button.Īnother ways is to use the command line. If you installed it from the Software Center, the easiest way to remove the application is from the Software Center itself. Now that you’ve learned to install VirtualBox, I should also mention the steps for removing it. sudo apt update & sudo apt install virtualbox-6.0 Now that you have the correct repository added, refresh the list of packages available through these repositories and install VirtualBox. Note: If you see an add-apt-repository command not found error, you’ll have to install the software-properties-common package. If you’ve read my article on checking your Ubuntu version, you probably know that ‘lsb_release -cs’ will print the codename of your Ubuntu system. Now add the Oracle VirtualBox repository to the list of repositories using this command: sudo add-apt-repository "deb $(lsb_release -cs) contrib" Sudo add-apt-repository “deb bionic contrib“ ![]() For example, Linux Mint 19 series users should use bionic and Mint 18 series users should use xenial. If you’re using Linux Mint or some other distribution based on Ubuntu, replace $(lsb_release -cs) in the command with the Ubuntu version your current version is based on. ![]()
