The possible categories are: mistranslation, assembly, other, device, graphic, socket, network, KVM, boot, vnc, debug, files, permissions, performance, kernel, peripherals, hypervisor. + +Looking at the bug report, the issue is that a multi-core FreeBSD guest hangs after a warm reboot on certain Linux KVM hosts. The problem occurs specifically with Xeon E5-26xx v2 processors but not others. So, it's related to how QEMU interacts with these CPUs under KVM. + +The user mentioned that the problem happens during SMP initialization after issuing a "reboot" command. They also noted that fully shutting down and restarting works fine. This suggests an issue during the reboot process, specifically in how multiple CPUs are handled. + +Since this is happening within a KVM environment and relates to CPU handling, it's likely tied to QEMU's management of virtual CPUs or interactions with the host's CPU architecture. The categories related to KVM would be 'KVM' itself or possibly something else like 'boot' since it's during the reboot process. + +But considering that the issue is about how the guest handles multiple CPUs after a reboot under KVM, the primary category should focus on the hypervisor aspect, which in this case is QEMU as the hypervisor for KVM. Alternatively, if it's a problem with CPU handling, maybe 'kernel' or 'peripherals', but since KVM is involved, 'KVM' seems more appropriate. + +Wait, but looking at the categories again: 'hypervisor' is also an option. Since QEMU can act as a hypervisor for KVM, perhaps that's a better fit. The issue might be in how QEMU handles SMP guests on specific host CPUs during reboots. + +Alternatively, considering it's about rebooting and CPU behavior, maybe 'boot' or 'kernel', but the primary environment is KVM. So between 'KVM' and 'hypervisor', I think 'hypervisor' is more accurate because the issue pertains to how the hypervisor (QEMU) manages the virtual machine, especially regarding CPUs. + +Wait, no, since QEMU runs under KVM, which is part of the Linux kernel's hypervisor support. Maybe 'KVM' is the category here as it's specific to the KVM acceleration and how QEMU interacts with the host's KVM for CPU management. + +But I'm a bit torn between 'hypervisor' and 'KVM'. Since the problem occurs under KVM, which is part of QEMU's functionality when using '-machine accel=kvm', perhaps 'KVM' is more specific. However, sometimes issues in QEMU related to virtualization are categorized under 'hypervisor'. + +Wait, looking at the categories again: hypervisor is listed as a separate category, so maybe that's better. + +But let me think about it differently. The problem is happening when using KVM acceleration within QEMU. So the issue might be specific to how QEMU handles the KVM virtualization for multiple CPUs on these Xeon v2 processors during reboot. Therefore, 'KVM' would be more precise as the bug relates to the KVM hypervisor's behavior in QEMU. + +Alternatively, if it's a problem with CPU handling, perhaps 'peripherals', but that doesn't seem right. No, peripherals are more about devices like USB or SCSI. So 'KVM' seems better. +</think> + +The issue pertains to how QEMU handles SMP guests on specific host CPUs during reboots under KVM, making the category: + +hypervisor \ No newline at end of file |
