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).
