hi all!
i'm having problems installing GuestAdditions. my host is a headless CentOS 5.6. i have installed 2 VM (Centos5.2 32b & centos5.2 64b, their kernel is 2.6.18-92.el5) both are headless. i have attached the VBoXGuestAdditions.iso to my VM. i do "mount -o loop /dev/dvd-hdb /usr/local/source" and then the iso is mounted on ../source. there i see the diferent files of the iso the ones for windows, solaris and Linux. so i do "sh VBoxLinuxAdditions.run" i see it is installing but then it prints this:
"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-2.6.18-92.el5".
So i do "yum install kernel-devel" and the version it installs is "2.6.18-238.9.1.el5". after this i try to acces these "new" kernel, when i can choose between the old one(2.6.18-92)and new kernel(2.6.18-238), but it hangs it never finishes loading.
any idea what it is going wrong?¿
thanks!!
