Allows for specifying compute node RAM
Currently we allow specifying ram per Overcloud VM. If the node is detected as ODL, we bump the RAM to a minimum of 10GB. There is a need to be able to specify the RAM per compute node in cases where we need controller RAM to be high, but want compute nodes to be low (like CSIT) - in order to keep the memory footprint as small as possible. Changes Include: - Adds '--virtual-compute-ram' argument that will override the '--virtual-ram' param for compute nodes - Fixes a bug where if ODL is used and RAM is overridden to 10GB for Control nodes, it was also accidentally being set for compute nodes - Modifies '--virtual-ram' to be '--virtual-default-ram' in order to clarify this parameter sets the default amount of RAM for all overcloud nodes which may be overridden by a role specific arg Change-Id: Ia36082aa2167d9897f3ec6753d08804352301c63 Signed-off-by: Tim Rozet <>
