GlanceConnectionFailed: Connection to glance failed: Error communicating with http://10.20.72.32:9292 timed out

When this happens, the volume gets stuck in “Uploading” state and never completes.

    vmware: Force chunked transfer for upload-to-image

    The upload-to-image operation downloads (using stream-optimized HTTP NFC
    transfer) the virtual disk corresponding to the volume to a pipe from
    where the glance image client reads the data for upload. Due to a recent
    change in the glance image client, success in seeking the input file
    object results in forgoing the chunked transfer in favor of regular
    transfer. The glance image client expects an IOError if the input file
    object is a pipe. Currently the pipe seek() is a NOP and this results in
    upload-to-image failure. This changes fixes such failures by throwing
    an IOError indicating an illegal seek.
