Are you at all trying to run a non standard kernel? The OS/kernel version settings on vmware are not just for for informational purposes, but instead vmware makes very specific assumptions about what clocking options (and possible other things) are configured in your kernel based on these settings. It assumes, for example that Redhat 5 does NOT use a tickless kernel and that all recent releases of Ubuntu do use a tickless kernel. If you choose a setting that is too far off from the kernel your running, you will have major clocking issues and your machine may not run. I discovered this when I had a VMware virtual machine from a hosting provider and was having problems. Finally, I was able to write a small program which did a select with a timeout, that would not run in the VM, but ran in other places. I called the hosting provider and asked them to read me the vmware config parameters for my VM and sure enough I was running CentOS 5 and they had configured my VM as Ubuntu. They changed that to Red Hat and all my problems went away. Nataraj
