(Or you run it in containers with podman, toolbox, and Flatpak. (So, do not use it unless it’s for 100% personal use only or if you pay Oracle for it under their terms.) Back to the problemĪs Silverblue’s OS partition is basically read-only, you cannot add software on top of the base except as RPMs using rpm-overlay. They release the extensions as personal use only and go after people (with lawyers) who use it for anything other than personal use. The licensing? Oracle intentionally muddles with it. Yeah, a lot of what’s in the extension pack is actually useful and provided by default in other VMs (such as qemu and anything powered by libvirt). VirtualBox itself is Open Source, but the extension pack adds “ USB 2.0 and USB 3.0 devices, VirtualBox RDP, disk encryption, NVMe and PXE boot for Intel cards”. Explanation of the (intentional) license issues The reason why Oracle doesn’t include it in VirtualBox is due to licensing. The filename is Oracle_VM_VirtualBox_Extension_Pack-6.1.12.vbox-extpack, found from However, VirtualBox’s extension pack (which is what is asking about) is not in an RPM, so you cannot overlay it on Silverblue. VirtualBox is in an RPM and can be installed with rpm-ostree. If you open a new virtual machine or already saved virtual machine without updating the extension pack with the previous version, an error message will be popped on the screen saying that VM will not start and also informs about USB2.0 and extension pack. So, in order to avoid such pop-ups, you need to disable USB2.0 controller for specific virtual machine or else you have to install or update the latest VirtualBox extension pack.I’m guessing probably knows some of this already (for the extensions pack case), but here’s some detailed background for everyone and some suggestions on what can do further down: Background info Experimental support or PCI Pass through on Linux hosts. You can perform remote booting on a computer through emulation of the Intel PXE boot ROM with support for the E1000 network card.ĥ.VirtualBox Remote Desktop Protocol enables you to run a virtual machine on one computer and you can view and control it from the other computer.VirtualBox Remote Desktop Protocol (VDRP) For that, you need to manually enable the controller and add devices for the USB devices connected to your system.Ģ. If you have USB host controller, then it allows you to get better performance from your USB 2.0 devices.
