Method and licensing for virtualization on disaster recovery server

Our customer has 2 servers - 1 running SBS 2011, the other running Windows 2008 R2 which is used as a terminal server for remote access and internal application publishing.

We would like to setup two virtual machines on an external server that their users can connect to in the event of a disaster situation.

My thought is that we can take a machine image of each server offsite.  Their data is already backed up offsite on a daily basis.  So we could restore the image plus incremental backups to a virtual machine and have all users connect from their home PCs using terminal services.

As I understand it, a Windows 2008 licence covers you for one physical and one virtual machine - do both have to be used on the same physical machine?  i.e. does their current 2008 licence cover them for having a virtual machine at another site?

And what's the score for SBS 2011?

Similarly, if they have TS CALs on the physical server - do we have to buy additional CALs for the virtual server - even if the virtual server is never running at the same time as the physical one?

Windows 2008 does cover you for one physical and one virtual, normally that virtual licenses is used on the host physical license.

But in the event of a disaster, the original Production site is down and off, so those licenses are not in use!

Check this Document although it's 2006

Customers only pay for active and running OS instances. Instances of applicable operating systems that are stored in virtual machines and are NOT active (e.g., for test/dev or disaster recovery) do NOT require additional licenses. This policy also applies to server applications such as BizTalk and SQL Server.

The final word will be with Microsoft Licensing.

Are assumption is our DR site, and most customers, do not have double the number of licenses, because they are not on, only for testing.
