Let's break it down step by step. + +First, the problem occurs in an Ubuntu 20.04.3 environment with virtio-scsi devices on a KVM guest. The issue is that during disk tests, when there's a failed path, the guest experiences miscompares. That suggests something is wrong with how SCSI commands are being handled between the host and guest. + +Looking at the comment by Halil Pasic, he mentions that prior to a specific commit (a108557bbf), QEMU wasn't building sense data correctly based on the host's SCSI status. This caused the guest to think a command succeeded even when it actually failed. He points out that this leads to corruptions in the guest's view of the storage. + +The key here is understanding what part of QEMU is involved. Virtio-scsi implies that it's related to the VirtIO SCSI driver, which is part of QEMU/KVM for virtualized SCSI devices. The problem arises from how sense data is generated and passed back when a command fails. This falls under the handling of SCSI commands within the hypervisor or QEMU itself. + +The commit referenced (a108557bbf) seems to be about inlining sg_io_sense_from_errno() into callers, which suggests it's modifying how sense data is built from error information. This indicates a change in how QEMU constructs and handles SCSI command responses, particularly when dealing with host-level errors. + +The comment also mentions that this doesn't fault the guest kernel or multipath components but points to an issue within QEMU's handling of SCSI commands on the host side. The proposed fix is through backporting patches, which are changes made to older versions of software (in this case, likely backporting a newer QEMU feature to an older release). + +Now, considering the categories provided: hypervisor seems like the most fitting since KVM is a hypervisor, and this issue relates to how QEMU, as part of the hypervisor stack, handles SCSI commands and their responses. The other categories like network, socket, or device (maybe storage devices) are relevant but not as precise as hypervisor. + +Therefore, the bug report is primarily about an issue within the hypervisor's handling of SCSI operations, specifically in QEMU's VirtIO-scsi implementation. +</think> + +hypervisor \ No newline at end of file |
