Hi Dan,

I attached my working vbox6 launcher from 22.10. just in case you need to look up more. (However, please be aware that some non-USB-Devices parts most probably differ from the setup that Johannes Schlatow describes) The USB-Devices part is the following:

<service name="ROM" label="usb_devices"> <child name="usb_devices_rom"/> </service>

I hope this helps you.

Cheers, Martin

I can't configure it with the GUI because the vertical resolution on this ThinkPad T430 is only 900 pixels and the vm config menu is too tall.

I see the screen size limitation is known...

That's a known limitation. I agree that it is inconvenient, so I keep it in the back of my mind. For regular Sculpt power users, it is not really a pressing issue since the /config/deploy file can be edited directly also (the graph is just a fancy frontend for editing this file)."

But not being a Sculpt power user, I could use some help. If I were able to use a larger screen and use the graph, what would I see in my vm config?

For reference, the log starts out fine:

[runtime -> vm -> vbox] main Log created: 2023-01-28T06:30:54.002000000Z ... [runtime -> vm -> vbox] 0x4222000 .. 0x4245fff: VBoxSharedFolders.so [runtime -> nic_router] [default] NIC sessions: 1

but then shows this error:
