# Generate OVA images
#
# OVA images are, by defintiion a tarball consisting of a disk image, OVF file
# and checksums. This step produces an OVA that is suitable for use with
# Cloud's that support the OVF specification.
#
# For this step, we re-use the VMDK's made in 040-vmdk-image.binary
# Switch on $ARCH to determine which ID and description to use in the produced
# OVF. We have fancy Ubuntu-specific IDs in the OVF specification, we might as
# well use them.
