"Give away" OS device to VirtualBox?

Question

virtual box

You can somehow "give" the device to Windows on virtualbox, that is, there is Ubuntu with VB installed with Windows, and there is Geforce GTX, and I need my GTX from under Windows in VB in the device manager.

Answer 1

this is called forwarding the video card in the hypervisor. It seems like VB does not support this thing

Answer 2

Hardware must support IOMMU (VT-d/AMD-Vi). Need a second monitor, tk. when forwarding to a virtual machine from Ubuntu, the card will not be available.
Dig in Google VGA Passthrough.
It is better to do not VirtualBox, but in KVM ( guide for example).

Answer 3

As far as I know, VB is not able to forward pci devices by definition. This can only be done using the bare-metal hypervisor.

Answer 4

XenServer also supports PCI Passthrough. As far as I know, only XenServer and KVM can forward the PCI bus to the guest OS.
