The user provided a detailed description of an issue they're encountering with QEMU during live migration involving storage. + +First, the error message mentions an assertion failure in block/io.c at line 1543: `bdrv_co_pwritev`, specifically when checking `!(bs->open_flags & BDRV_O_INACTIVE)`. This suggests that the code is trying to write data but finds that the block device's open flags include the inactive flag, which isn't allowed in this context. + +The user describes their setup: using QEMU 2.7 and 2.10.rc3 with libvirt 3.0.0 and 3.2.0. They're performing a live migration with `virsh migrate` including the `--copy-storage-all` option, which I know is used to copy storage data during migration. + +The problem occurs after calling `bdrv_inactivate_all()`, but some coroutine (`mirror_run`) continues writing dirty disk data to an NBD server. This causes the assertion because the block device is inactive but still being written to. + +Looking at the categories provided, we have several options like 'device', 'storage', 'network', etc. The issue here is related to how storage is handled during migration, particularly with block devices and their states (active vs inactive). Since the problem arises from operations on the block layer during live migration, which involves copying data over the network but is fundamentally a storage issue. + +I think it's important to note that while network or NBD might be involved in the process of moving the data, the core issue is with how the block devices are being managed after deactivation. The assertion failure points directly to the block device handling code (`block/io.c`), indicating a problem within QEMU's storage subsystem. + +Therefore, the most appropriate category here would be 'storage'. This aligns with the fact that the bug report centers around issues during live migration when dealing with storage devices and their state transitions. +</think> + +The issue is related to block device handling during live migration. The assertion failure occurs because a block device that's supposed to be inactive is being written to, which should not happen. This points directly to an issue in how the block layer (storage) is being managed in QEMU. + +Answer: storage \ No newline at end of file |
