The user provided some code snippets and error messages related to live migration with VirtIO SCSI. Let me go through the information step by step. + +First, the error message is an assertion failure: "Assertion `!r->req.sg' failed." This happens during live migration when using VirtIO. From the code provided, I see that this assertion is inside the function scsi_generic_save_request in hw/scsi/scsi-generic.c. The code checks if r->req.sg is null and asserts it. + +Looking at the code for scsi_req_enqueue_internal in hw/scsi/scsi-bus.c, I notice that when a request is enqueued, it sets req->sg by calling get_sg_list on the bus info. For VirtIO SCSI buses, this method returns &req->qsgl. The problem seems to be that once sg is set, it's never cleared unless certain conditions are met. + +The user also mentions that the error occurs when put_scsi_requests is called during migration because it invokes both virtio_scsi_save_request and scsi_generic_save_request. This causes the assertion to fail since req->sg isn't null anymore. + +So, the issue arises because the VirtIO SCSI code doesn't clear the sg list after enqueuing a request. The assert in scsi_generic_save_request is checking that sg is null, but it's not always the case. Therefore, this seems like a bug related to how requests are handled during migration, specifically with VirtIO's SCSI implementation. + +Looking at the possible categories provided: device, graphic, socket, network, KVM, boot, vnc, debug, files, permissions, performance, kernel, peripherals, hypervisor. The issue is about VirtIO SCSI handling during migration, which falls under SCSI device management. Therefore, it should be classified under 'device' or more specifically under 'peripherals', but since the primary component here is the VirtIO bus and SCSI requests, I think 'device' is appropriate. + +Wait, but wait—VirtIO devices are typically handled through their respective drivers, so maybe it's better to classify this as a 'device' issue. Alternatively, since it's related to how the hypervisor interacts with the SCSI device during live migration, perhaps 'hypervisor' could be another option. But considering that the core problem is within the SCSI request handling and VirtIO bus code, which are part of the device emulation in QEMU, I think 'device' is the correct category. +</think> + +The bug report involves an assertion failure during live migration with VirtIO SCSI due to the sg list not being cleared, which points to a device-related issue. + +**Step-by-Step Explanation:** + +1. **Error Analysis**: The error occurs because `r->req.sg` isn't null when it should be according to the assert in `scsi_generic_save_request`. + +2. **Code Path Identification**: The `sg` list is set during request enqueuing via `get_sg_list` for VirtIO buses and isn't cleared elsewhere. + +3. **Context of Failure**: This happens during live migration when saving SCSI requests, indicating a problem with device state management during hypervisor operations. + +4. **Classification**: Since the issue pertains to how VirtIO devices handle SCSI requests, it falls under 'device' category. + +**Answer:** +The bug report is classified under: device + +**Final Answer:** +device \ No newline at end of file |
