Public bug reported: The libvirt driver creates flat disks as sparse by default. However, it always returns over_committed_disk_size=0 for flat disks in _get_instance_disk_info(). This incorrect data ends up being reported to the scheduler in the libvirt driver's get_available_resource() via _get_disk_over_committed_size_total().
_get_instance_disk_info() should use allocated blocks, not file size, when calculating over_commited_disk_size for flat disks. ** Affects: nova Importance: Undecided Status: New ** Tags: libvirt low-hanging-fruit -- You received this bug notification because you are a member of Yahoo!
