    VMware: specify chunk size when reading image data

    When reading OVA image data from Glance without specifying chunk size,
    nova-compute tries to read the entire tar stream in memory because this
    is how the tar fileobject is implemented. This patch fixes this by
    specifying the chunk size to be 64KB.
