I just tried to install the VMware tools on openSUSE 10.3 (Linux kernel 126.96.36.199) so the virtual machine would survive more than 10 days on an ESX server and failed. If you have the same problem, the solution is here.
Errors you’ll see during the installation otherwise:
The directory of kernel headers (version @@VMWARE@@ UTS_RELEASE) does not match your running kernel (version 188.8.131.52-0.2-default). Even if the module were to compile successfully, it would not load into the running kernel.
