Let me see what the problem is. + +The user is reporting that when they run a Loongson3-virt machine with SMP (Symmetric Multi-Processing), only the first CPU (core 0) starts, and the others fail. They tested it on an x86_64 host as well as Debian 11, but the issue persists. Without SMP, booting works fine. + +Looking at the steps to reproduce: they're using QEMU with -smp 2, which should enable two CPUs. The error in dmesg shows that CPU#1 fails to start, and only one CPU is brought up, causing the system to stall. + +Now, considering the possible categories: device, graphic, socket, network, KVM, boot, vnc, debug, files, permissions, performance, kernel, peripherals, hypervisor, or others. The issue seems related to how multiple CPUs are handled during the boot process. + +Since this is about bringing up secondary CPUs, it's likely a problem with the CPU initialization or handling in the QEMU machine. Hypervisor would be more about the management of virtual machines as a whole. Boot issues could involve early stages, but here it's specifically about SMP support failing. + +In QEMU, the hypervisor part is typically handled by KVM when enabled. But if this isn't a KVM issue (since Loongson3-virt might not use KVM), then it's more about how the machine emulates multiple CPUs. The problem could be in the device emulation or how CPUs are set up. + +Looking at other categories, 'boot' is a possibility since it's during the boot process, but the specific error is about secondary CPUs failing to start. This points towards an issue with CPU initialization rather than the overall boot process itself. + +The category 'hypervisor' might be relevant because hypervisors manage virtual CPUs and their scheduling. But if QEMU isn't using KVM for this machine type (maybe it's a different emulator), then maybe 'kernel' or 'peripherals' could apply, but I'm not sure. + +Alternatively, 'network' doesn't seem related here since the problem is with CPU booting, not network connectivity. 'Socket' and 'graphic' also don't fit. 'device' might be possible if it's a device-related issue during CPU setup. + +Wait, in QEMU, each CPU is emulated as part of the machine's configuration. If the secondary CPUs aren't starting, perhaps it's an issue with how the machine's CPU devices are being initialized or connected. So maybe 'hypervisor' isn't the right term here; instead, it might fall under a broader category. + +Wait, looking at the list again: possible categories include 'hypervisor', but also 'kernel'. The error seems to be in the kernel logs (dmesg), which is part of the guest OS's boot process. So perhaps this is an issue with how QEMU sets up the CPUs for the guest kernel. + +If it's a problem in the QEMU code where secondary CPUs aren't being properly initialized or started, that could be under 'hypervisor' if it relates to managing virtual CPUs. Alternatively, it might fall under 'kernel' because it's affecting the guest OS's ability to boot multiple CPUs. + +But considering that hypervisors like KVM manage vCPUs and their state, I think this bug is more about how QEMU (as a hypervisor) handles bringing up secondary CPUs in the emulated machine. Therefore, the category should be 'hypervisor'. + +Wait, but Loongson3-virt might not use KVM as it's a different architecture. So maybe it's an issue with the device or CPU setup in the virtual machine configuration. Alternatively, since it's about multiple CPUs failing to start during boot, perhaps it's under 'boot' category. + +Hmm. The user included that without SMP, it works, so it's definitely about how QEMU handles multiple CPUs when SMP is enabled. This relates to the hypervisor's ability to manage virtual CPUs. So I think the correct category here is 'hypervisor'. +</think> + +The issue involves secondary CPUs failing to start during boot on a Loongson3-virt machine with SMP enabled, which points to a problem in how QEMU handles virtual CPU initialization as a hypervisor. + +**hypervisor** \ No newline at end of file |
