Host OS: Arch Linux x64 Guest OS: Windows 10 x64 Scenario:
* Host bios firmware: Tried with pure UEFI firmware and with CSM enabled. * Virtual Machine scheme (xml)<https://pastebin.com/J0zZEvwm> * CPU: Intel i5 4590T (Haswell) -> It doesn't have GVT-d nor GVT-g, so I'm trying the legacy mode. * GPUs: 1- Intel HD Graphics 4600(headless - no cable attached). Primary host GPU. 2-RX580(HDMI cable connected). -> I'll keep this to the host. * IOMMU groups list<https://pastebin.com/3JRnAxpR> * Seabios log <https://pastebin.com/pDXbK5rn> * Kernel parameters: intel_iommu=on iommu=pt efifb=off simplefb=off nofb vfio-pci.ids=8086:0412,8086:0c0c Things I tried: 1- Compile latest rc2 qemu. 2- /etc/modprobe.d/iommu_unsafe_interrupts.conf -> "options vfio_iommu_type1 allow_unsafe_interrupts=1" 3- Set "pc-i440fx-2.2" to several versions. 4- Compile Seabios with some specific patch I found online. 5- /etc/modprobe.d/kvm.conf -> "options kvm ignore_msrs=1" 6- Set x-vga to "yes" and "no". I know it doesn't make difference on legacy mode. 7- Some qemu arguments(e. g. -nographic) regarding graphics, setting all those to off.
