VMware Workstation 8.0.0 vs Linux Kernel 3.1.0
VMware Workstation 8.0.0 won't work on Linux Kernel 3.1.0 out of the box. But, some clever guy coded a very neat script that you can use to patch the workstation in a few easy steps:
$ cd /tmp
$ wget http://18.104.22.168/vmware3.1rc.sh
$ chmod +x vmware3.1rc.sh
That should patch the modules source, recompile it and start the vmware services. I've also attached the courtesy copy of the script to this article, in case the remote location becomes unavailable.
