Prereq

1. Virtual Box
2. qemu - brew install qemu
3. NooBaa release's OVA

Steps

1. deploy the OVA to Virtual Box, don't start the machine
2. Check the VMDK path in the Machine -> Settings -> Storage. Select the VMDK location.****
3. run the following command qemu-img convert -O qcow2 "vmdk location/NooBaa-1.4.1-disk1.vmdk" "/NooBaa-1.4.1-disk1.qcow2"

another option (Jacky 25/6/2017)

1. Don't deploy the OVA - just extract using tar -xvf NooBaa-build.ova
2. do step 3 with the vmdk file:
3. qemu-img convert -O qcow2 "vmdk location/NooBaa-build-disk1.vmdk" "target location/NooBaa-build-disk1.qcow2"
