• Explore debootstrap, nbd and chroot based systemvm template building. PoC shows promise, builds template under 5mins. (vs 30-60mins before), refer to PoC tree for export logic too.
• Instead of bundling all 3x systemvmtemplates, we can bundle one of the hypervisors and build/export the image for other hypervisors using qemu-img upon cloudstack-management pkg install/upgrade (we use qemu-img to convert the template to different hypervisor images during build too):
  • Bundle qcow2 file in cloudstack-management pkg
  • Use export mechanism that uses qemu-img, tar and bzip2 to export to other hypervisor formats - ova and vhd. Check for qemu-img compatibility/feasibility for all support mgmt server distros. This can be done during automated template upgrades/updates or when cloudstack-management pkg is installed or upgraded.
  • In testing, we found this entire process of conversion takes 10-30seconds in total; which may significantly save on bandwidth of over 1G in total cloudstack-management pkg/file being downloaded
• During packaging, this can simplify things so if systemvm.iso is deprecated then we bundle the ova only when -D systemvm or -P systemvm is enabledenable
