KVM/qemu Windows 10 guest with NVidia 2080Ti passthrough is running with some glitch and crashed the arch host within 60 minutes. Still investigating the cause. VFIO is a Linux kernel userspace driver framework used by QEMU to make devices directly assignable to virtual machines. When devices are bound and unbound to the driver, the driver should call vfio_add_group_dev() and vfio_del_group_dev() respectively:. It may also help to uninstall the Windows vfio-balloon device/driver completely, and then restart the VM a couple times. VFIO provides a secure, IOMMU based interface for user space drivers, including device assignment to virtual machines. I'm trying to install modern Radeon drivers on the guest.
