Add two new configuration knobs that control the logical and physical sector sizes advertised by virtio-blk devices to the guest: block_device_logical_sector_size (config file) block_device_physical_sector_size (config file) io.katacontainers.config.hypervisor.blk_logical_sector_size (annotation) io.katacontainers.config.hypervisor.blk_physical_sector_size (annotation) The annotation names are abbreviated relative to the config file keys because Kubernetes enforces a 63-character limit on annotation name segments, and the full names would exceed it. Both settings default to 0 (let QEMU decide). When set, they are passed as logical_block_size and physical_block_size in the QMP device_add command during block device hotplug. Setting logical_sector_size smaller then container filesystem block size will cause EINVAL on mount. The physical_sector_size can always be set independently. Values must be 0 or a power of 2 in the range [512, 65536]; other values are rejected with an error at sandbox creation time. Signed-off-by: PiotrProkop <pprokop@nvidia.com>
