VMware Tools Auto-Upgrade Error

When you attempt to auto-upgrade a CentOS/RHEL guest’s VMware Tools in VSphere’s client interface, you may find yourself faced with an error in the Recent Tasks window:


Initiated VMware Tools install or upgrade. Target: servername. Error Upgrading VMware Tools


Check your current kernel version, and compare it to the kernels in /boot. If your current kernel version is not the same as the newest one in /boot, reboot, and try again!

Example:

# uname -r
2.6.18-194.11.4.el5
# ls /boot/vmlinuz*
/boot/vmlinuz-2.6.18-194.11.4.el5 /boot/vmlinuz-2.6.18-194.17.1.el5 /boot/vmlinuz-2.6.18-194.17.4.el5
# shutdown -r now


Since my currently running kernel is not the newest one, the auto-updater throws up on the upholstery and quits. After rebooting (which by default loads the newest kernel, unless you’ve set up something odd), I was able to auto-update VMware tools without a problem.
