Okay, so I need to classify this bug report about QEMU. The user has provided possible categories, and I have to pick one based on the given bug report. The bug is titled "Stop execution on unhandled exceptions" in qemu-system-aarch64. From what I know, QEMU is an emulator and virtualizer that can run different architectures, including AARCH64. Now, when it comes to handling exceptions, especially in emulators or virtual machines, this often relates to how the hypervisor manages guest OS issues. Looking at the categories provided: kernel, peripherals, hypervisor, etc. I'm thinking about what "unhandled exceptions" typically involve. Exceptions are usually managed by the operating system or the CPU, but since QEMU is emulating this for a virtual machine, it's likely that unhandled exceptions would cause the hypervisor (QEMU in this case) to stop execution. So, considering that, I'm leaning towards 'hypervisor' as the category. This is because the hypervisor is responsible for managing the guest OS and handling such issues when they occur. If an exception isn't handled by the guest, it's QEMU's job to stop execution to prevent further issues. hypervisor
