Betreff: [vbox-dev] How add device or driver (PDM) to VirtualBox

Hi,

I ask about this before but don't get any answer...

How add new device/driver to Virtualbox?
Is there a someone who understand how PDM works?

I compile VBoxSampleDevice.cpp and add it to VirtualBox but system(ubunutu 14) don't show any new device.
To add dll to Virtualbox I use:
VBoxManage setextradata global VBoxInternal/PDM/Devices/[[1]]/Path g:\VirtualBox\out\win.amd64\release\obj\testingDevice\VBoxSampleDevice.dll

Also I try to add device using copy of Virtio device. I copy code of DevVirtioNet.cpp modify it (change some names), build dll and add to VirtualBox:
VBoxManage setextradata global VBoxInternal/PDM/Devices/[[3]]/Path g:\VirtualBox\out\win.amd64\release\obj\testingDevice\testingDevice.dll

But still nothing change in guest system.

In DevVirtioNet.cpp I found a lot of code which set a lot of parameters connected with PCI. I try understand this code but this take, a lot of time.

I also found that I have to set which driver will be use in system also in configuration of virtual machine.
I try to set net ethernet cart type but in VBoxManage I found code which allow using only build in drivers so I can't set "My" modified Virtio driver.

There is really no instruction or documentation how it's works?

I will be really gratefull for any help or instruction how add new device to VirtualBox.


Best regards,
Marcin
