The user is experiencing a blue screen when running the Windows 10 install DVD in QEMU. They provided details about the QEMU command-line options they're using and some error messages from the crashes. + +First, the blue screen occurs right after the initial setup dialog, which suggests that something goes wrong during the boot process. The specific errors mentioned are "DRIVER IRQL NOT LESS OR EQUAL" and "KMODE EXCEPTION NOT HANDLED." These types of blue screens usually indicate kernel-mode issues in Windows, often related to device drivers or hardware compatibility. + +Looking at the QEMU command line, they're using various devices like USB controllers (ICH9), a VirtIO balloon, VirtIO serial port, and an ICH9 IDE controller. They're also using the qxl-vga for graphics. The CPU configuration includes KVM=off, which might be relevant since KVM is a hypervisor. + +I know that when running Windows under QEMU, especially with certain devices or configurations, there can be issues where the virtual hardware isn't compatible with what Windows expects. For example, if a device isn't properly emulated or lacks necessary drivers, it could lead to these types of blue screens. + +The fact that they're using VirtIO devices might be part of the problem because VirtIO requires specific drivers in the guest OS. If those aren't installed or recognized correctly, it can cause kernel-mode exceptions. Alternatively, if the host's CPU doesn't support KVM acceleration and QEMU is falling back to TCG (which they are since accel=tcg), that could lead to performance issues or instability. + +Another point is the use of ICH9 USB controllers. Maybe there's a bug in how these are emulated under certain conditions, causing driver issues for Windows 10. Or perhaps the lack of proper device passthrough or necessary kernel modules loaded on the host affecting the guest's ability to handle hardware. + +Given that the errors are related to kernel-mode exceptions and driver IRQL issues, this seems more like a problem with the hypervisor (QEMU) not correctly emulating the hardware, which falls under the 'hypervisor' category. This is because QEMU/KVM acts as a hypervisor when using KVM acceleration, even though in their case KVM is off. + +So, putting it together, the blue screen is likely due to an issue with how QEMU's hypervisor (or lack thereof) handles certain devices or virtualization, leading to Windows encountering hardware-level errors during boot. Therefore, the appropriate category for this bug report would be 'hypervisor.' +</think> + +hypervisor \ No newline at end of file |
