The user is experiencing an issue where running QEMU versions 1.4.0 and onwards on Linux kernels 3.2.x leads to "kernel_hung_tasks_timout_secs" messages and an unresponsive QEMU process under heavy I/O load. They tried upgrading the kernel to 3.8.0-27-generic, which resolved the issue. The problem can be triggered with certain workloads like using 'spew' for I/O and running apt-get commands in parallel. + +The command-line example they provided includes enabling KVM (-enable-kvm), VNC, Virtio devices (network and block), and other standard QEMU options. They also mention that the monitoring session doesn't respond to reset or termination commands; it needs a hard kill. + +Now, looking at the categories: The issue is about QEMU becoming unresponsive with kernel hung task messages. This seems related to how the host OS's kernel interacts with the KVM hypervisor since KVM is involved (given -enable-kvm). Kernel hung tasks usually relate to issues within the Linux kernel itself, possibly in handling I/O or scheduling, especially under heavy loads. + +The problem occurs when using KVM and happens on specific kernel versions. Upgrading the kernel fixed it, which suggests a potential bug in the older kernels' interaction with KVM or QEMU. Since this is about the hypervisor (KVM) interacting with the host's kernel, the category 'kernel' might be appropriate. However, since KVM is part of the hypervisor layer and the issue relates to how the host kernel handles tasks under heavy I/O, it's more aligned with the host kernel's behavior. + +Wait, but the user is using QEMU with KVM enabled, so it's a Type 1 hypervisor (KVM) running on top of Linux. The hung task message comes from the host kernel, indicating that a task didn't release CPU for a certain period. So this seems like a kernel issue rather than a problem within QEMU itself. + +Alternatively, could it be under 'hypervisor' since KVM is the hypervisor component? But the root cause seems to be in the Linux kernel's handling of tasks, possibly related to I/O scheduling or resource management when running KVM guests. Therefore, it's more accurately categorized under 'kernel' as the issue arises from the host OS's kernel behavior. + +So, after considering all this, the most appropriate category is 'kernel'. +</think> + +kernel \ No newline at end of file |
