Bluetooth virtualbox

Hello,

A virtual machine does not directly use the hardware of its host machine. A "simple" VM has all its components fully virtualized through software (CPU, RAM, graphics card, network card, ...) and is independent of the host hardware. Thus, having a Bluetooth or WiFi card or any other hardware on the host does not indicate that the virtual machine has this hardware. For example, the virtualization software (VirtualBox) will simulate a "standard model" RJ-45 network card for the virtual machine even if the host accesses the Internet via WiFi. Another misconception is believing that the virtual machine runs games on the host's GPU, whereas it does not; the virtual machine only has a virtualized "standard VGA model" GPU running on the host's CPU.

It is possible to perform a "redirection" of host devices, whether they are USB, SATA (HDD/SSD storage), or even PCI components. This can depend on the virtualization software used. When this is done, the component in question is disconnected (inaccessible) to the host.

Furthermore, I can’t say much more at the moment as it depends on many factors:
• Is the Bluetooth card a PCI or USB component (internal/external)? Since you are on Linux, you can check this with

lsusb

and

lspci

.
• Is the Bluetooth card paired with the WiFi chip (same PCI/USB component)? This is often the case with Intel models. If so, redirecting the component will result in losing both WiFi and Bluetooth on the host.
• If it's a PCI component, it will be even more complicated
• There’s also the question of the Bluetooth component's support by the virtual machine's operating system.

Thank you for your replies.

It seems quite compromised then, have a nice day :)
