![]() ![]() Cool, I thought! I've got two NVIDIA Quadro FX graphics cards (with SLI bridge connection in place, which I hope isn't causing the grief) and would like to dedicate the 2nd graphics card to the guest OS, so that I can use OpenGL features within Photoshop et al. I recently realised that it's possible to pass through a PCI-express device to guest OS's running in Virtualbox. Giving a guest OS direct access to graphics card It is my understanding (and last option I can think of) that changing this boot option might get rid of the following error message in /var/log/kern.log vboxpci: No IOMMU domain (attach) Documentation I've seen says to edit /boot/grub/menu.lst, which seems to be relevant only for grub 1.x, as I don't have that file. How can I turn on the intel_iommu setting in the Linux kernel? I run a Debian host, using the grub2 bootloader. ![]()
