Hi, ramkrishna1.
What part is not supported by VMware?
Basically, from my own perspective, the feedback to management was to "not" mod the /etc/vmware/config file. The approach I recommended was to mod the .vmx file via manual editing.
As to the approach used to modify the .vmx file, that's a TBD based on the individual SA's preference. There may be a PRO to scripting, but the PRO (fast, easy) is also a CON, if the mod(s) are faulty. So, with that said, my recommendation: the target is the .vmx file, while the method of "payload" delivery is left to the SA, with a recommended Best Practice of manual edit.
Is this what you were referring to?
Thx.
