I'm pretty sure you can (if you have a vt-d capable cpu) use the intel IGP for Linux and a nvidia card dedicated for the vm using kvm and vfio-vga drivers.
Unfortunately I can not test this myself as I have a 4770k cpu in my gaming computer and it does not support vt-d.
- ComputerGuru 11y agoNo, unfortunately I have a useless brick of a GTX 680 Lightning laying on my desk as we speak and an R9 Fury in the mail because that's not the case. I have a separate, basic PCI-E graphics card in the machine as the host GPU, but nothing you do will get an nVidia to pass through. I haven't tried KVM, but I have tried Xen and ESXi, and my reading tells me the same is true for KVM. I'm using an older AMD/ATi HD 7790 in the meantime, it passes through just fine. (Hint/Note: don't pass through the on-board HDMI, that'll give you BSODs and kernel panics to no end.)
- DCKing 11y agoThe article mentions that KVM/Qemu has an option you pass in to work around the GPU detection. Might be worth checking out before you spend that money.
