This type of image mimics a more conventional Linux distro like Debian or Ubuntu, where you have packages and you keep updating or installing them as needed.

by booting a Gparted liveCD in your Virtualbox VM, as the default ext4 image is too small (technical reason: the filesystem does not contain enough inodes at this size) to allow online resizing ( ext4 can be enlarged without using a liveCD if it is big enough at the start) With ext4 you can increase the partition size to your heart's content, but you will need to do it “offline”, i.e. NB: With Imagebuilder, the size of the read-write partition is irrelevant as all packages are embedded in the squashfs read-only partition that is enlarged as needed, so 128MB is available for config only.

It's a very convenient way of tracking snapshot(master) to have the latest and greatest, and the only practical way to do so for most other devices supported by OpenWrt, so this is more or less the best “choice” for OpenWrt veterans that have deployed many devices and are using the imagebuilder already. Since you have Virtualbox anyway, why not have a Debian or Ubuntu VM and use the Imagebuilder too.
#Virtualbox interface install
You can install with sysupgrade, and not lose any of your “installed packages” as you have integrated them in the base firmware image. Squashfs images are neat when you are using the Imagebuilder to integrate all packages you want in a single re-settable image. For any additional help, use VirtualBox's documentation.If you need more space for data you can always increase the virtual disk size and add a data partition (which will be preserved on sysupgrade), or even better add more virtual drives you would use just for storage. Overall, the setup for VirtualBox nested virtualization is a fairly simple process. Be sure to execute the command in the same folder where VirtualBox is installed.
#Virtualbox interface windows
If you run VirtualBox on a Windows OS, execute the command without the dollar sign. On a Linux system, the command to enable nested virtualization is: $ VBoxManage modifyvm -nested-hw-virt on If you confirm there are no other hypervisors installed, but still encounter issues, then manually enable nested virtualization at the command line. PowerShell Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-Hypervisor -All If you use Hyper-V to run Docker containers, then you may need to open an elevated Command Prompt window and run some alternative commands: DISM /Online /Disable-Feature:Microsoft-Hyper-V If you must disable Hyper-V then open a PowerShell session with elevated permissions, then enter the following command: Remove-WindowsFeature Hyper-V Nested virtualization will not work if VirtualBox is on a Windows system with Hyper-V activated. First, verify that the system has no other hypervisors enabled. Occasionally, the option to enable nested virtualization for a VM is grayed out.ĭisable hypervisors. VirtualBox users sometimes encounter a grayed-out Enable VT-x/AMD-V checkbox, as shown in Figure 1. Grayed-out checkbox for nested virtualization Now the VM is ready for nested virtualization. Select the Processor tab, then the Enable Nested VT-x/AMD-V checkbox and click OK.
#Virtualbox interface series
The system settings are divided into a series of tabs. Click on the System icon, and the dialog box displays the VM's system settings. The Settings dialog box contains a series of icons that run along the left side of the window. Once you create the VM to host the nested copy of VirtualBox, open the VirtualBox Manager, right-click on the VM and then choose the Settings command from the shortcut menu. You must create a VM before you can enable nested virtualization. Generally, admins launch nested virtualization in VirtualBox on a per-VM basis. Version 6.1 adds support for Intel processors. Oracle supports nested virtualization on a limited basis in version 6.0 but only for certain AMD CPUs. To use VirtualBox nested virtualization, run version 6.1 or higher. This strategy protects the virtual environment from VMs that overwhelm memory or other resources. Then the user can create VMs on an as-needed basis but cannot consume more resources than what you allocate to the VM with the nested VirtualBox copy. With nested virtualization, you can give a user access to a VM that runs a nested copy of VirtualBox. To set up VirtualBox nested virtualization, you install VirtualBox onto the OS, create a VM and then install a copy of VirtualBox on that VM.

VirtualBox users can virtualize Oracle VM Server or KVM within its VMs. VirtualBox is a free, open source hypervisor from Oracle that runs on a variety of VMs and supports nested virtualization.
