That's unusual because PCI tends to be more prescriptive than regulations like HIPAA or GLBA or SOX. If you are an IT person, why should you care what Visa thinks about anything? If your company handles credit cards then you need to care because it leaves PCI-approved auditors to interpret and decide how virtualized servers and applications might be subject to PCI security requirements. Yikes."
