Footnotes:
1. Starting with RHEL 7, RHEL will have SVVP support only under specific subscription programs. If you are unsure whether your subscription model includes support for Windows guests, please contact customer support. RHV and OSP have full support and ship SVVP certified drivers. In addition, the Red Hat Enterprise Linux 7 Server version which you are using must be listed as a supported virtualization technology for running Windows Server at Windows Server Catalog - Server Virtualization.
2. Microsoft Windows operating systems certifications only apply to all RHEL 6 releases and all RHEL 5 releases.
3. For best performance, the para-virtualized I/O drivers (virtio-win) are required to be installed in the Windows guests. The drivers are made available as images in the Supplementary channel of the Red Hat Enterprise Linux host OS. Please refer to this article for details. Please see the Microsoft SVVP site for certification details.
