Scott,

You don't need Copy Services Manager, you just need a storage subsystem capable 
and enabled for Global Mirror, which is independent and outside of any 
operating system.  z/VM disks can be part of a consistency group, just as VSE, 
z/OS, Linux or TPF disks can.

While z/VM can't use consistency groups -- z/OS and zLinux can with CSM
(Copy Services Manager)  ....    I'm currently involved in a project where
we have this running on a zLinux guest to be able to flash with consistency
groups.
