qemu: fix bugs in blockstats The documentation for virDomainBlockInfo was confusing: it stated that 'physical' was the size of the container, then gave an example of it being the amount of storage used by a sparse file (that is, for a sparse raw image on a regular file, the wording implied capacity==physical, while allocation was smaller; but the example instead claimed physical==allocation). Since we use 'physical' for the last offset of a block device, we should do likewise for regular files. Furthermore, the example claimed that for a qcow2 regular file, allocation==physical. At the time the code was first written, this was true (qcow2 files were allocated sequentially, and were never sparse, so the last sector written happened to also match the disk space occupied); but modern qemu does much better and can punch holes for a qcow2 with allocation < physical. Basically, after this patch, the three fields are now reliably mapped as: 'capacity' - how much storage the guest can see (equal to physical for raw images, determined by image metadata otherwise) 'allocation' - how much storage the image occupies (similar to what 'du' would report) 'physical' - the last offset of the image (similar to what 'ls' would report) 'capacity' can be larger than 'physical' (such as for a qcow2 image that does not vary much from a backing file) or smaller (such as for a qcow2 file with lots of internal snapshots). Likewise, 'allocation' can be (slightly) larger than 'physical' (such as counting the tail of cluster allocations required to round a file size up to filesystem granularity) or smaller (for a sparse file). A block-resize operation changes capacity (which, for raw images, also changes physical); many non-raw images automatically grow physical and allocation as necessary when starting with an allocation smaller than capacity; and even when capacity and physical stay unchanged, allocation can change when converting sectors from holes to data or back. Note that this does not change semantics for qcow2 images stored on block devices; there, we still rely on qemu to report the highest written extent for allocation. So using this API to track when to extend a block device because a qcow2 image is about to exceed a threshold will not see any changes. Also, note that virStorageVolInfo is unfortunately limited to just 'capacity' and 'allocation' (we can't expand it to add 'physical', although we can expand the XML to add it there); historically, that struct's 'allocation' value has reported file size for qcow2 files (what this patch terms 'physical' for a domain block device), but disk usage for raw files (what this patch terms 'allocation'). So follow-up patches will be needed to make storage volumes report the same allocation values and get at physical values, where those differ. * include/libvirt/libvirt-domain.h (_virDomainBlockInfo): Tweak documentation to match saner definition. * src/qemu/qemu_driver.c (qemuDomainGetBlockInfo): For regular files, physical size is capacity, not allocation.

getstats: add new flag for block backing chain This patch introduces access to allocation information about a backing chain of a live domain. While querying storage volumes for read-only disks could provide some of the details, we do NOT want to read() a file while qemu is writing it. Also, there is one case where we have to rely on qemu: when doing a block commit into a backing file, where that file is stored in qcow2 format on a host block device, we want to know the current highest write offset into that image, in order to know if the disk must be resized larger. qemu-img does not (currently) show this information, and none of the earlier block APIs were extensible enough to expose it. But virDomainListGetStats is perfect for the job! We don't need a new group of statistics, as the existing block group is sufficient. On the other hand, as existing libvirt releases already report 1:1 mapping of block.count to <disk> devices, changing the array size could confuse older clients; and even with newer clients, the time and memory taken to report additional statistics is not always necessary (backing files are generally read-only except for block-commit, so while read statistics may change, sizing statistics will not). So the choice here is to add a new flag that only newer callers will pass, when they are prepared for the additional information. This patch introduces the new API, but it will take more patches to get it implemented for qemu. * include/libvirt/libvirt-domain.h (VIR_CONNECT_GET_ALL_DOMAINS_STATS_BACKING): New flag. * src/libvirt-domain.c (virConnectGetAllDomainStats): Document it, and add a new field when it is in use. * tools/virsh-domain-monitor.c (cmdDomstats): Use new flag. * tools/virsh.pod (domstats): Document it.
