The user is performing a memory stress test on the VM with 16 vCPUs. They inject an MCE to simulate hardware errors, which triggers the host's MCE and sends SIGBUS to the VM. QEMU then takes control and checks the broadcast attribute using cpu_x86_support_mca_broadcast(). + +The issue arises because when QEMU injects MCE to all vCPUs simultaneously, it can't ensure that all vCPUs enter the MCE handler in sync, causing the VM to panic. The user suggests increasing monarch_timeout but notes it depends on vCPU count and system scheduling. They question why QEMU needs the broadcast attribute for MCE and if it's necessary to always signal all vCPUs. + +The core problem seems related to how QEMU handles MCE across multiple vCPUs, specifically in KVM virtualization. The bug involves QEMU's behavior when processing MCE events, which is a hypervisor feature since KVM runs under the host's kernel and requires proper handling of such exceptions. + +Looking at the categories, "hypervisor" fits because this issue pertains to how the hypervisor (KVM) manages machine check exceptions across virtual CPUs. It's not about assembly translation or performance but rather about the hypervisor's functionality in managing hardware exceptions in a VM environment. +</think> + +hypervisor \ No newline at end of file |
