As per VMware support - we need to install OS Specific Pack (OSP - VMTools) for certain Linux Versions
My Linux is (SUSE 9 SP3) here..
http://packages.vmware.com/tools/esx/4.1u1/sles9/i586/index.html
As of now There is no certified method to "Re-install only Balloon driver i.e vmmemctl module" in linux..
In the case "VMTools shows OK - but Balloon driver does not work" -> Only way is to re-install "VMtools"
Few Guest OS - does not work via "upgrade VMTools form VC" - Need OS specific VMTools packs to be installed (like above URL)
Thank you for your views...
