This patch improves the output of 'kvm setup' as follows:
[penberg@tux kvm]$ ./kvm setup
kvm setup creates a new rootfs under /home/penberg//.kvm-tools/.
This can be used later by the '-d' parameter of 'kvm run'.
usage: kvm setup [name]
[penberg@tux kvm]$ ./kvm setup test-box
A new rootfs 'test-box' has been created in
'/home/penberg//.kvm-tools/test-box'.
You can now start it by running the following command:
kvm run -d test-box
[penberg@tux kvm]$ ./kvm setup test-box
Unable to create rootfs in /home/penberg//.kvm-tools/test-box: File exists
