I’ve been getting a lot of questions on this script that makes it possible to install VMware tools without rebooting. I must admit that it’s a really smart way to surpress the automatic reboot. But please keep in mind that it’s not VMware Tools that needs the reboot but the actual OS that needs the reboot. Why? VMware tools includes device drivers! The “tools” itself is a service that can easily be restarted but that’s clearly not something you would do with a device driver. And don’t forget about what happens to your nic driver when it’s being updated… yes, all network connection will drop.
So I do think this script can be usefull if you want to do a manual reboot at a certain time. But please be sure reboot the VM as soon as possible, cause not rebooting the VM can and probably will cause problems.
