Here are the steps that allowed me to install VMWare WS6 on FC8.
# uname -r
# rpm -qa 'kernel*'
If these 3 do not match, then
.kernel-<version>
.kernel-devel-<version>
.kernel-headers-<version>
# yum remove kernel*-<oldversion>.fc8
eg: yum remove kernel-2.6.23.1-49.fc8
# yum install kernel kernel-devel kernel-headers
# yum install gcc
# yum install gcc-c++
download and install latest vmware-any-any-<version>
http://knihovny.cvut.cz/ftp/pub/vmware/
unzip to same dir as vmware-distrub (fixed the vmmon error)
# ./runme.pl
this should automatically be called from runme.pl, but ...
# ./vmware-install.pl
Done.
Regards,
Scott.
