Trying to install Guest Additions I see:
sh ./VBoxLinuxAdditions.run
The headers for the current running kernel were not found. If the following module compilation fails then this could be the reason. The missing package can be probably installed with yum install kernel-devel-2.6.18-194.el5
Building the main Guest Additions module [FAILED]
Trying to install kernel-devel-2.6.18-194.el5 I see:
yum install kernel-devel-2.6.18-194.el5
Setting up Install Process No package kernel-devel-2.6.18-194.el5 available. Nothing to do
What can be done with that?
Host OS is Windows 7 64 bit, Guest OS is RedHat 5.5 64 bit.
