Hey All I was just playing with the new VMWare server but could not build vmmon.ko: LD [M] /tmp/vmware-config1/vmmon-only/vmmon.ko make: Leaving directory `/usr/src/kernels/2.6.17-1.2157_FC5-i586' cp -f vmmon.ko ./../vmmon.o make: Leaving directory `/tmp/vmware-config1/vmmon-only' Unable to make a vmmon module that can be loaded in the running kernel: insmod: error inserting '/tmp/vmware-config1/vmmon.o': -1 Invalid module format There is probably a slight difference in the kernel configuration between the set of C header files you specified and your running kernel. You may want to rebuild a kernel based on that directory, or specify another directory. For more information on how to troubleshoot module-related problems, please visit our Web site at "http://www.vmware.com/download/modules/modules.html" and "http://www.vmware.com/support/reference/linux/prebuilt_modules_linux.html". Execution aborted. However, checking the running kernel and installed sources I get: [[email protected] ~]# uname -r 2.6.17-1.2157_FC5 [[email protected] ~]# rpm -qa | grep kernel kernel-devel-2.6.17-1.2157_FC5 kernel-2.6.16-1.2096_FC5 kernel-2.6.17-1.2157_FC5 kernel-doc-2.6.17-1.2157_FC5 Has anyone else run into a similar problem?
