-1 windows server 2008 STD volume license with backward compatibility to Windows server 2003 STD.
-100 windows server 2003 CALs
With these licenses, as I understand, I can install any 2003/2008 windows server on a host and uses as a VM management only, then I can install another 2003/2008 on a guest serving client access as a file server or any other purpose. In this case, should the host and guest have the exactly the same OS? For example, can I install 2008 on host, 2003 on guest?
I'm also wondering what is the exact boundary of saying 'host as only management'. can I keep files? what about the backup process where other servers need to access the host to back up files on the host?
The virtual server is Oracle VirtualBox.
