When I try to start a virtual machine, vmware player complains that vmmon module is the wrong version. I have uninstalled vmware-player and vmware-modules and run emerge for vmware-player-5.0.1.894247 and vmware-modules-271.1-r1 Reproducible: Always Steps to Reproduce: 1. start vmware 2. select a virtual machine 3. click on "Play virtual machine" Actual Results: An Error dialog is displayed that says: Version mismatch with vmmon module: expecting 271.0, got 264.1. You have an incorrect version of the `vmmon' kernel module. Try reinstalling VMware Player.
After lsmod showed that a newly built vmmon wasn't being used, I ran "rmmod", then "modprobe". This corrected the problem.
