It should be mentioned that it's important not to accept the default volume 
group name when using LVM as that will lead to a collision in a case such 
as this where the VG name of both host and guest might end up beeing 
"VolGroup00". I hope RHEL/Centos 6 chooses better defaults based on the 
hostname for example.
