The user provided detailed steps and error messages. + +First, I'll go through the description. They set up a live migration between two QEMU instances on the same server using zstd compression. Both source and destination are configured similarly, enabling KVM with 10 CPUs and 50G memory. They used tap interfaces for networking. + +The errors reported during migration include: +- Source side: Failed to save SaveStateEntry with id 2 (ram), unable to write to socket due to a connection reset by peer. +- Destination side: Unknown combination of migration flags (0x0), decompress data failed, and load of migration state failed with an operation not permitted. + +Looking at the error messages, the key points are the failure in writing the socket on the source and decompression issues on the destination. The mention of "ram page flag 0x0" suggests something is wrong during memory handling, possibly related to how pages are being transferred or compressed. + +The categories given include various areas like mistranslation, assembly lowering, network, KVM, etc. Since this is about live migration and compression, it's likely a kernel issue because live migration involves the hypervisor (KVM) interacting with the host's memory management. The problem occurs during data transfer between instances, which could involve how QEMU handles memory pages or compression in the kernel mode. + +I think the primary issue here relates to the hypervisor's handling of memory during live migration. Since it's about saving and loading state sections and decompression failing, this points towards a problem in how the hypervisor (KVM) manages the migration process, possibly with how the compressed data is being handled or the flags involved in the process. + +So, considering all this, the most fitting category would be "hypervisor" because it's directly related to KVM's functionality during live migration. +</think> + +hypervisor \ No newline at end of file diff --git a/results/classifier/deepseek-2-tmp/reasoning/hypervisor/1562653 b/results/classifier/deepseek-2-tmp/reasoning/hypervisor/1562653 new file mode 100644 index 000000000..9898e62c2 --- /dev/null +++ b/results/classifier/deepseek-2-tmp/reasoning/hypervisor/1562653 @@ -0,0 +1,21 @@ +<think> +Alright, I'm trying to classify this bug report for QEMU. The issue happens on Ubuntu 15.10 where a VM hangs when it's allocated 1TB or more of memory. Let me look at the details. + +First, the user set up an Ubuntu 15.10 host with high specs: 8 CPUs and 4T of RAM. They created a VM with 16 vCPUs and 1TB of memory using KVM. The problem occurs when the VM starts; it hangs if memory is >=1TB, but works fine below that. + +Looking at the XML config, everything seems standard except for the high memory allocation. The panic stack mentions functions like async_page_fault, ioread32_rep, and others which seem related to memory management or I/O operations. This suggests a possible issue with how QEMU handles large memory allocations on the host. + +The user tried switching to Red Hat 7.2 as the host OS, and the VM worked even with up to 3.8T of memory. So it's more likely an issue specific to Ubuntu 15.10 rather than a general QEMU problem. + +Considering the categories provided: hypervisor, kernel, performance, etc. Since this is KVM-based (as seen in the XML), but the issue seems related to how the host OS handles large memory allocations and page faults. However, the bug occurs in the guest VM, so it might be a translation or handling issue within QEMU. + +Wait, could it be a memory management problem in the hypervisor layer? Or perhaps an issue with how the host's kernel interacts with QEMU when dealing with such high memory. Alternatively, maybe it's related to device drivers or I/O operations since some functions in the stack trace relate to I/O. + +But looking back at the categories, 'hypervisor' is a possible category. Since KVM is part of the hypervisor layer (Linux kernel), and this issue might be due to how the host handles memory ballooning or allocation under heavy load. The memballoon device is also mentioned in the XML, which suggests that memory management could be a factor. + +Alternatively, it could be 'performance' if the system can't handle the high memory efficiently. But since it's causing a hang rather than just slow performance, maybe it's more related to how the hypervisor (KVM) manages resources under certain conditions. + +I think the most fitting category is 'hypervisor' because the problem occurs within the KVM environment and relates to memory allocation and management in the VM. +</think> + +hypervisor \ No newline at end of file |
