If you've got the free resources available, it may be simplest to install Helion CE again and use a vm plan file to specify what size your compute node needs to be. A good example of this can be found in this install guide:

http://docs.hpcloud.com/helion/openstack/1.1/install/laptop/demo/

Basically, a vm_plan.csv file contents might look like this:

,,,,2,5120,,Undercloud
,,,,2,6144,,OvercloudControl
,,,,2,6144,,OvercloudControl
,,,,2,6144,,OvercloudControl
,,,,2,3072,,OvercloudSwiftStorage
,,,,2,3072,,OvercloudSwiftStorage
,,,,4,6144,,OvercloudCompute
,,,,4,6144,,OvercloudCompute


...where "4,6144,,OvercloudCompute" tells you the compute nodes are 4vcpu, 6GB RAM.

Once you've got a plan file, you just have to point the installer at it. For example:

bash -x /root/work/tripleo/tripleo-incubator/scripts/hp_ced_host_manager.sh --create-seed --vm-plan /root/vm_plan.csv 2>&1|tee seedvminstall.log
