@ssumpf sorry, I’m struggling to assemble an `option` for a couple of partitions on the disk (I don’t want to use the whole disk, just 1st and 3rd partitions with `biod_boot` and linux `root` filesystems) πŸ˜… Could you please provide an example how to correctly do this in the `option` file? πŸ™ ---

Yes, EFI is supported (Windows/Linux guests). ---

You should be able to pass two partitions to VBox7. I would follow Johannes approach [https://genodians.org/jschlatow/2021-04-23-start-existing-linux-from-sculpt:](https://genodians.org/jschlatow/2021-04-23-start-existing-linux-from-sculpt:) - Create the _disk.vmdk_ using partition 1 and 3 of your system ```auto VBoxManage internalcommands createrawvmdk -filename disk.vmdk \ -rawdisk /dev/ -partitions 1,3 -relative ``` - Add two instead of one `block` node the _runtime_, e.g., ```auto + block sda1 | label: 1 | io_buffer: 8M + block sda3 | label: 3 | io_buffer: 8M ``` - Route the block-sessions in the option to the correct partitions in the `+ connect` node ```auto + block | label_last: 1 | + child nvme-1.part | label: 1 + block | label_last: 3 | + child nvme-1.part | label: 3 ``` This is just a rough sketch and I will leave figuring out the details up to you. ---

Thank you a lot! πŸ™ Will try that today! πŸ‘ ---

@ssumpf it works great now! Thank you! πŸ™ I even dared to connect the `gpu` to `intel_gpu`, `play` and `record` to the `mixer`, and `rom (mesa)` to `mesa_gpu-intel` (had to tweak that one to start the component on my i7-10700 first)! So VirtualBox starts and loads my system, though I still have some challenges ahead. Because my Linux system is a bit unusual: Artix with OpenRC, XLibre and i3 as a window manager. Looks like it shows only the background picture and nothing else despite of actually running the apps I start with `dmenu`. πŸ€” Though with `mesa_gpu-cpu` it was extremely slow but at least draw a Telegram window once πŸ™ƒ But I guess this thing is on the VBox itself, rather than on the Genode πŸ‘Œ ---

> [@G0retZ](#): > > Looks like it shows only the background picture and nothing else despite of actually running the apps I start with `dmenu`. πŸ€” Ok, turned out the issue was in a `picom` running using `glx`. Disabled it and now everything is fine! 🀩 ---

@Nos: I looked into the Youtube stutter issue and in my case a reconfiguration of the driver for the Intel HDA soundcard in the VirtualBox7 guest fixed the stutter effects. Please have a look at [#5906 - vbox6: audio gets stuck in Ubuntu 24.04 guests - genodelabs/genode - Codeberg.org](https://codeberg.org/genodelabs/genode/issues/5906) ```auto cat /etc/modprobe.d/intelhda.conf options snd-hda-intel position_fix=1 ``` This is caused by [VirtualBox Intel HD Audio and PipeWire Incompatibility / Audio broken after increasing ram to 5 GB / No sound after latest updates - PipeWire Bug? - #31 by sxd - VirtualBox - Whonix Forum](https://forums.whonix.org/t/virtualbox-intel-hd-audio-and-pipewire-incompatibility-audio-broken-after-increasing-ram-to-5-gb-no-sound-after-latest-updates-pipewire-bug/18211/31) [Previous page](https://genode.discourse.group/t/virtualbox-for-the-brave/338.md?page=1)
