In the mean time I am finding this to be more cumbersome than useful. Pretty much, there will need to be some form of end-user setup for this for at least the foreseeable future.
#BOINC VIRTUALBOX DRIVER#
You have to make sure the standard GPU driver on the host side doesn't bind to or initialize the GPU you want to pass through, and you have to have things configured just right inside the VM too so that it doesn't do anything that would cause the passed-through GPU to mess things up for the host OS (GPU initialization is extremely complicated compared to most other hardware). Regardless, there's more involved than just flipping a switch in the hypervisor on a system with proper IOMMU support.
#BOINC VIRTUALBOX DRIVERS#
The typical design used by most hypervisors doesn't actually use GPU pass through, but does OpenGL translation/emulation in such a way that the display output gets composited properly (IOW, the VM display window looks to the host system's drivers like any other windowed OpenGL app), which in general means that OpenCL, CUDA, and Vulkan aren't really supported for anything but GPU passthrough. Other hypervisors might have some form of sharing, but I don't think it's very likely that it will properly support OpenCL or CUDA (or Vulkan for that matter).
Note that the VirtualBox approach is all or nothing, as is the mechanism used by QEMU and Xen. It's non-trivial to detect from userspace of course, but you can in theory check the kernel logs to see if it's there or not. Last I checked, the NVIDIA drivers refuse to work with GPU's they detect as 'virtualized' (which includes Xen's GPU support, and QEMU and VirtualBox passthrough) unless they're Quadro branded cards.Īs far as the presence of IOMMU support (VT-d is just Intel's fancy branding for an IOMMU), the Linux kernel itself knows whether it's there or not, and reports it in the kernel logs. See also Understanding VT-d: Intel Virtualization Technology for Directedīeyond all of that, there's driver issues too.
