recreating the stemcell with the new property to disable bosh micro (unused with cloudstack) reduces the base stemcell size
export BOSH_MICRO_ENABLED=no
Might improve provisioning time ?

Since VHD is not on a dynamic format, this will have no effect on the VHD size.

Latest qemu-img version (2.0) available on Ubuntu Trusty is now compatible with XenServer dynamic VHD format.
It also can convert the cloudstack-xen-ubuntu.raw file created by “image_create” stage to VHD without the img => qcow2 => raw conversion.
Dynamic disk type reduces VHD size to 1.2GB.

The Azure "prepare_vhd_image_stemcell" apply.sh with dynamic vhd mode and bzip2 should work for Cloudstack stemcells.
#!/usr/bin/env bash
set -e
base_dir=$(readlink -nf $(dirname $0)/../..)
source $base_dir/lib/prelude_apply.bash
rm -f $work/root.vhd
# Convert raw to dynamic vhd
