Let me start by reading through the problem described. + +The user is encountering a crash in their VM when a broadcast Machine Check Error (MCE) occurs. They're using QEMU with 16 vCPUs and inject an MCE during a memory stress test. The host raises an MCE, sends SIGBUS to the VM, and QEMU takes control. QEMU then checks the broadcast attribute via cpu_x86_support_mca_broadcast(). + +The issue seems to stem from QEMU broadcasting the MCE event to all vCPUs, but since they're part of the same process on the host, there's no guarantee that all vCPUs will handle it synchronously. This can lead to the VM panicking because not all CPUs might enter their MCE handlers at the same time. + +The user suggests expanding monarch_timeout as a fix but points out it depends on vCPU count and system scheduling, making it tricky. They're confused about why QEMU needs the broadcast attribute for MCE since it seems like only one vCPU is signaled. They ask if just delivering the LMCE to a specific vCPU would be better. + +Looking at the possible categories: mistranslation, assembly lowering, device, graphic, socket, network, KVM, boot, vnc, debug, files, permissions, performance, kernel, peripherals, hypervisor, and other. + +The problem is related to how QEMU handles MCE events across multiple vCPUs. This seems like a virtualization issue, specifically with KVM or the hypervisor's handling of machine checks. Since it's about VM behavior when processing errors across CPUs, the category likely falls under 'hypervisor' as it deals with managing virtual machines and their resources. + +I don't think it's mistranslation because that would relate to code translation issues between architectures. It's more about how events are handled in the hypervisor layer. So, I'll go with 'hypervisor'. +</think> + +hypervisor \ No newline at end of file |
