Making VMware Keep Correct Time. Until recently, the only sure-fire way to make sure VMware kept the same time as your hardware clock was to use a cron job which polled a time server for the correct time and then reset the VMware/Linux clock every few minutes. That’s been fixed, and we’ll show you how to patch the boot loader to fix it. But, first, while you’re using WebMin, let’s disable the time-setting cron job. From the main WebMin menu, choose Hardware->System Clock. In about the middle of the page is an option to Synchronize (the time) on Schedule. Just set it to No and Save your change. Now go to the command prompt on your server and make certain you are logged in as root. Edit the boot loader (nano -w /boot/grub/grub.conf) and move down to line 16 which begins with the word “kernel.” Edit that line so that it looks like the following and save your change (Ctrl-X, Y, then Enter). Then reboot your system (shutdown -r now). HINT: Everything after “noapic” is new stuff to be added, and it all must be appended to the end of the existing line.kernel /vmlinuz-2.6.9-34.0.2.EL ro root=LABEL=/ acpi=off noapic nosmp nolapic clock=pit
