The user mentioned that when they use `qemu-aarch64-static` to run an arm64v8/openjdk image on their x86 machine, the container hangs and produces a core dump. They noticed that with older versions of QEMU (like 2.5.0 and 2.11.1), this issue doesn't happen. The problem occurs specifically with version 2.11.91. + +Looking at the provided categories: mistranslation, assembly, device, graphic, socket, network, KVM, boot, vnc, debug, files, permissions, performance, kernel, peripherals, hypervisor, and others. + +The user's issue is related to running an ARM64 image on x86 using QEMU. The hang and core dump suggest a runtime issue rather than a build or translation problem. Since the core dump occurs when executing Java code (`javac`), it's likely a segmentation fault within the guest OS, which could be due to incorrect memory handling or a bug in the emulation. + +The fact that older versions of QEMU work fine points towards a regression introduced in the newer version (2.11.91). This suggests an issue with how certain instructions or system calls are emulated. However, since the problem occurs during execution, it's probably not a mistranslation issue because mistranslation would likely cause issues earlier, possibly during the initial setup or when running more basic commands. + +Looking at the categories, 'hypervisor' relates to QEMU acting as a hypervisor for the virtual machine. If there's an issue with how the hypervisor handles certain operations in newer versions, it could lead to hangs or crashes. Alternatively, 'kernel' might be relevant if the problem is within the kernel emulation. + +But considering that the user is using Docker and QEMU together, which involves device drivers and possibly KVM (for hardware acceleration), but they're using static qemu so maybe not KVM. The issue could also relate to how devices are emulated or how the filesystem is handled. + +Wait, another angle: the core dump indicates a crash in the guest OS. So perhaps it's an issue with how QEMU handles certain system calls or memory mappings. If the newer version has changes in the device emulation (like VirtIO components), that could cause problems when running Java which might be making specific syscalls. + +Alternatively, 'performance' doesn't seem right because it's a crash, not just slowness. 'Boot' is about starting up, but the issue occurs after booting into the container and running `javac`. + +The user also tried to get a core dump by snapshotting the filesystem and then using a different QEMU version. That suggests that the problem is specific to their setup with the newer QEMU. + +Given all this, I'm leaning towards 'hypervisor' because it's about how QEMU manages the virtual machine environment. The crash could be due to an issue in the hypervisor layer when running certain operations under the newer QEMU version. +</think> + +The bug report involves a core dump and hang when using a specific QEMU version, which suggests an issue with the hypervisor layer managing the VM. + +hypervisor \ No newline at end of file |
