Let me go through the details step by step. + +The user reported that their guest OS (Windows 7 64-bit) seems suspended after the host's oom-killer was triggered due to a memory-intensive process. The host is using QEMU version 5.1.0 and Linux kernel 5.5.13. After the oom-killer freed some memory, the guest became unresponsive. + +The user mentioned that they can telnet into the QEMU monitor, which shows the status as "running." However, checking the registers repeatedly shows no changes, indicating the VM isn't actually executing instructions. The host's CPU usage by QEMU is around 4%, and strace logs show a lot of ioctl calls related to KVM_IRQ_LINE_STATUS on various file descriptors, along with some ppoll calls timing out. + +They also noted that IRQ 0 in the monitor info is incrementing rapidly, which is associated with the system clock. The frequency matches what a Windows 7 guest might use. The user believes the VM is effectively paused despite appearing to run, and the host's activity is causing this state. + +The possible categories are: mistranslation, assembly, other, device, graphic, socket, network, KVM, boot, vnc, debug, files, permissions, performance, kernel, peripherals, hypervisor. + +Now, considering the issue involves the oom-killer freeing memory and the guest VM pausing. The symptoms point towards a problem with how QEMU handles low memory conditions, especially related to KVM (since they're using KVM IRQs). The host's strace shows KVM-specific ioctl calls, which are part of the kernel-based virtual machine functionality. + +The fact that the VM isn't progressing and registers aren't changing suggests a problem in the hypervisor layer, possibly when handling memory pressure. Since KVM is involved here, it seems like the issue falls under the 'hypervisor' category because KVM is the hypervisor used by QEMU for hardware acceleration. + +I don't think it's related to network, sockets, or graphics since those aren't mentioned. It also doesn't seem like a performance issue in terms of speed but rather a halting problem after memory management. Boot and VNC issues are unlikely here. +</think> + +hypervisor \ No newline at end of file |
