Let's see what the issue is. + +The user reported a race condition during shutdown in QEMU when starting multiple VMs with libvirt. The VMs use kernel and initrd and perform a poweroff -f. Some QEMU processes get stuck in ppoll(), which indicates they're waiting on some I/O but aren't proceeding, causing the hang. + +Looking at the provided backtrace, it shows that the process is stuck in qemu_poll_ns, called by os_host_main_loop_wait, then main_loop_wait, and so on. This suggests an issue with how QEMU's event loop or polling mechanisms are handling shutdown under certain conditions, especially when multiple VMs are running concurrently. + +The user mentioned bisecting and found a specific commit related to block graph changes during drain sections. They also noted that another commit might be involved but the problem persists even in the latest master. Reproduction was done on x86_64 and s390x, indicating it's architecture-agnostic. + +Given the categories: mistranslation, assembly lowering, device, graphic, socket, network, KVM, boot, vnc, debug, files, permissions, performance, kernel, peripherals, hypervisor, other. + +The issue relates to the shutdown process and QEMU processes hanging. Shutdown in QEMU is typically handled by the main loop and I/O handling. The race condition suggests a concurrency issue during cleanup or event processing. + +Looking at the categories, KVM is about virtualization support, but this seems more related to how QEMU handles its own process termination rather than hypervisor-specific issues. 'Boot' might be involved since it's about VM startup, but the problem occurs during shutdown. + +The key here is that multiple VMs are being shut down in parallel, causing a race condition. This likely involves how resources are being managed or cleaned up across different components of QEMU, possibly within the main loop handling I/O and events. Since this seems to be an issue with the event loop not properly terminating when it should, perhaps due to resource management during shutdown. + +I don't see clear indicators pointing to assembly lowering or mistranslation errors here. It's more about how QEMU handles its own processes during shutdown under load, which could relate to concurrency issues in the main loop or I/O handling. + +Considering all this, the most fitting category is 'other', as it doesn't neatly fit into the specific categories like KVM, network, etc., but rather points to a general issue with process management and event loops. +</think> + +other \ No newline at end of file |
