If your host system uses Time Stamp Counter and Virtual Machine guests use kvm-clock, then you should not use ntp on the guest. But what if you sync the physical host to a good Internet time source and just sync the virtualized guest to itself?

How to change tires in Gran Turismo 5

One of the best things you can do for any car is to give it better shoes. 500+ horsepower is useless if you can’t get that power to the ground. While in the tuning shop, you can buy tires and it will ask if you want to install them now. This is one way to change the tires, but many races require a specific type of tire.
