Step 4: Run ./build_xva.sh
--------------------------
This script prpares your nova xva image. This script can be run on a separate machine
and copied to dom0. If you run this on a different machine, copy the resulting xva
file to tools/xen/xvas/[GUEST_NAME].xva (by default tools/xen/xvas/ALLINONE.xva)
It is likely that for XS6 you will need to build_xva.sh on a separate machine due
to dom0 space constraints.
Step 5: Run ./build_domU.sh
