In any case, it will be cheaper to upgrade those Licenses to SA than it would be to purchase a VDA license.

This just shows the mess that MS licensing is in. Let's ignore the FPP as that doesn't count and I'm expecting to be able to assign a Win 7 license from Select to the thin clients. The client have already purchased Windows 7 via Select so it's a sunk cost. Key query here is; "do I need a VDA license for XP Pro"? I'm hoping not and that it's only a requirement for Windows 7.

FPP can be used for VDI if: 1) The physical server on which the virtual desktop is installed is assigned to 1 user. This is obviously nuts, but it is legal. 2) You assign a FPP to a device, and you use that device to access to the VM *under the condition that* you don't move that VM around. It can only be present on 1 server. So - no vmotion/xenmotion or load balancing. So - for every device that has an OEM windows license that you've "upgraded" with your volume license that counts as 1 license to access a VM, but that VM can only go on 1 server. So - for your PCs, you could leave them as is with these caveats above - point 2 is important. You might consider that OK; you might only have 1 main server or accept that each user's VM will only be available from 1 server. Each of the thin clients (as they don't have an OEM license assigned) needs to have a VDA license. As does any corporate smartphone/tablet. Bear in mind your VDA license is a cost per device, per year. You may consider that pt 2) is a PITA - you can solve that by getting SA for those VLs. With VDA & SA you get (drum roll Animal please.) . Install Windows 7/Windows Vista/Windows XP virtual machines on any combination of hardware and storage . Unlimited movement between servers and storage . Access corporate desktop images from non-corporate owned Windows-based PCs (home use, but not those deluded Mac users. splitters) . The primary user of a Windows VDA device has extended roaming rights, which means that the Punter can access their VDI desktop from any device outside of the corporate environment, such as a home PC or an internet kiosk (even if they have a Mac) . Eligibility for other Software Assurance products, such as MDOP and Windows Fundamentals for Legacy PCs . Single Windows VDA license allows concurrent access for up to 4 VMs . Reassignment rights to another device after 90 days, or in the case of end-point failure . Dynamic desktop licensing enabled through KMS/MAK activation & indeed, access to Enterprise versions of Windows. . Unlimited backups of both running and stored VMs (woo) . Includes Software Assurance (SA) benefits such as 24x7 call support, training vouchers, trips to disney land*, rocket ships to mars* etc. Note the "outside of the corporate environment" - a roaming license lets your punter use their VDA/SA license to access their desktop from their tablet/smartphone *until they bring it into the office* - then it needs a license.

My query is, do they need a VDA license for XP Pro? It would be delivered to both desktops PCs and thin clients. The client has Windows 7 via Select Agreement. No SA. They don't want to roll out Win 7 yet due to app compatibility so that's not an option. Anyone done this already? Pointers to MS documents would be great.
