https://bugzilla.kernel.org/show_bug.cgi?id=102301 Bug ID: 102301 Summary: Shutting down a Windowvs 10 virtual machine (with VGA passthrough) causes a hard crash, every time Product: Virtualization Version: unspecified Kernel Version: 4.1.4 Hardware: Intel OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: kvm Assignee: virtualization_kvm@xxxxxxxxxxxxxxxxxxxx Reporter: will.marler@xxxxxxxxx Regression: No I'm using libvirt and virt-manager to manage the VM; the VM is running using qemu. I am using VGA passthrough, and it works very smoothly. Until it's time to shut down; when I shut down the VM (either by virt-manager force power off, or from within the guest using start -> shut down), the host crashes.
