Alright, so I need to classify this bug report for QEMU. Let's see what the issue is. The title says: "nVMX: QEMU does not clear nVMX state through KVM(L0) when guest(L2) trigger a reboot event through I/O-Port(0xCF9)". From what I understand, nVMX stands for Nested Virtualization Management Extensions. It's related to virtualizing hypervisors, which is part of the KVM (Kernel-based Virtual Machine) functionality in QEMU. The problem description mentions that when the guest (which is L2 in a nested virtualization setup) triggers a reboot by writing to I/O port 0xCF9, QEMU doesn't clear the nVMX state through KVM(L0). So, this is about how the hypervisor handles reboots and maintains its state. Looking at the possible categories provided: mistranslation, assembly lowering, device, graphic, socket, network, KVM, boot, vnc, debug, files, permissions, performance, kernel, peripherals, hypervisor, and other. The key here is that this issue relates to KVM's handling of nVMX state during a guest reboot. Since it's about the interaction between QEMU (which uses KVM for hardware acceleration) and the nested virtualization state management, it falls under the KVM category. I don't think it's related to assembly lowering or mistranslation because those are more about code translation issues. It's also not a network or graphic issue. The reboot is triggered through an I/O port, but that's just the method; the core issue is with how KVM manages its state during this event. So, the category should be KVM. KVM
