Hi, I am running VMware player on CentOS 5.4 and its working fine. However it does not allow me to increase the RAM more than 3GB. It keeps throwing error stating- "Requested memory size is greater than allowed maximum of 3072 MB. Could not initiate memory hot plug." I understand from few threads that 32bit OS has this kind of limitation but I am able to understand why I am seeing this issue when I am using 64bit OS and VMware player is also for 64bit. Regards Hersh
