vga-passthrough

(I haven't used LG, so these are general VFIO considerations). I mantain a guide for setting up VFIO (https://github.com/saveriomiroddi/vga-passthrough), which I frequently use. My conclusion is: for machines that are compatible with it, VFIO works very well. The technology itself is stable, so working on photoshop/game development etc. (from a technological perspective, there's no distinction between the two tasks) is not distinguishable from working on native. I had VFIO on 4 machines I think, and one had problems which I couldn't solve, while the others worked well. When used with QEMU, it requires some system settings and QEMU flags etc., so it's a bit annoying, but it's straightforward and documented process. To put it in another way: if one wants to use VFIO seriously, it's best using hardware known to work well, rather trying to cr

An overall good introduction/guide is: https://github.com/saveriomiroddi/vga-passthrough. The most complete guide is probably the Arch Linux one: https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVM....

Basically you need relativly new hardware. IOMMU is a must. (for intel) Here is a guide from some other user: https://github.com/saveriomiroddi/vga-passthrough was really helpful but I needed to give up since my mainboard was too stupid and my graphic card didn't worked as I wanted. I could install the OS but it bootlooped after installing any driver. I used an asus b350-m mainboard with a AMD Ryzen 5 1500x + a radeon r9 280 (thaiti based basically the same as an hd7970) and it didn't worked since my mainboard only had one pci express 16x which meant that the "better" card needed to be used for the main os. You can use the first slot card for the os but it might not always work (hardly hardware dependant). Having a good mainboard is way more important for it to work.

VirtualBox will likely not support it for a very long time (assuming they will ever do it), as VGA passthrough has some host requirements (configuration-wise), that I think would be too much to handle for a virtualization product. I use QEMU and it works without any issue; to be specific, in hundreds of boots, it hung only a couple of times, which is very well within issues with windows itself rather than the platform. Also, it typically runs via a single script. The crux is to have the correct hardware (some hardware just doesn't work well), and to use a correct software setup (most important thing: if you use a GPU for passthrough, forget about using it on the host at all). The information around is unfortunately very scattered and often outdated. I suggest to use those two sources: - https://github.com/saveriomiroddi/vga-passthrough
