The bug report mentions that QEMU hangs during a build of NixOS SD card image specifically when using `qemu-aarch64`. + +First, let's understand what each category means: + +- **mistranslation**: Issues with incorrect semantic mapping from source architecture to IR/target in user-mode. +- **assembly**: Problems during assembly lowering. +- **other**: Any bug that doesn't fit into other specific categories. +- **device**: Bugs related to device handling. +- **graphic**: Graphics-related issues. +- **socket**: Socket-related bugs. +- **network**: Network-related problems. +- **KVM**: Issues with KVM hypervisor. +- **boot**: Booting issues. +- **vnc**: VNC server/client issues. +- **debug**: Debugging related bugs. +- **files**: File handling problems. +- **permissions**: Permission-related issues. +- **performance**: Performance bottlenecks. +- **kernel**: Kernel-related bugs. +- **peripherals**: Issues with hardware peripherals in the VM. +- **hypervisor**: Bugs in the hypervisor layer. + +The bug report states that QEMU hangs during a specific build step, which involves compiling through QEMU. The problematic line is in `make-ext4-fs.nix`, and when this runs, the qemu process uses 100% CPU but doesn't perform any I/O. It's stuck in some syscall for over 10 hours. + +The user tried using a static package from AUR and is now compiling upstream QEMU to see if the issue persists. They also mentioned discussing with others who couldn't help, so it might be a more complex or less common bug. + +Now, considering the behavior: CPU usage is maxed, no I/O activity, stuck in a syscall. Since it's during image creation (compiling through QEMU), it could relate to how QEMU handles certain operations during build processes. + +Possible categories that fit: + +1. **mistranslation**: If the issue arises from incorrect translation of instructions, but since it's hanging on a syscall and not necessarily about instruction mapping, this might not be the best fit. +2. **performance**: The CPU is maxed out, so maybe a performance-related bottleneck. But performance issues usually have known causes like loops or inefficient code, which isn't directly mentioned here. +3. **boot**: Since it's during a build for NixOS on ARM, but the issue occurs in the build process, not necessarily during booting of the VM. +4. **network**: No network activity was indicated, so probably not related. +5. **device/peripherals**: If the syscall is related to device I/O or peripherals, this could be it. However, since there's no I/O activity mentioned, perhaps not. +6. **hypervisor**: QEMU as a hypervisor might have issues in how it handles certain operations under heavy load, leading to hangs. + +Alternatively, the bug could fall into 'other' if it doesn't fit neatly into any specific category. But considering that it's related to the build process within QEMU and causing high CPU usage without I/O, maybe it's a performance issue or perhaps something with device emulation. + +Wait, but the user is compiling binaries through QEMU, which might involve device emulation for certain syscalls. If QEMU isn't handling these syscalls efficiently, it could lead to a hang. + +Alternatively, since the process is stuck in a syscall without I/O, maybe it's waiting on some resource or not handling an interrupt correctly, which could be a hypervisor issue. + +But looking back at the categories, 'hypervisor' might not cover build-time hangs. Maybe 'other' is safer here. +</think> + +The bug report describes QEMU hanging during a build process with high CPU usage without I/O activity. The issue doesn't fit into specific categories like performance or network but could be related to device emulation or hypervisor behavior. However, since it's more about build-time and not a clear category, 'other' is the best fit. + +**other** \ No newline at end of file |
