Re: Proposal: drop support for Hyper-V 2008R2

Hello, I've been getting familiar with Hyper-V recently and have gotten stymied by inconsistencies in its API. While Hyper-V has V1 and V2 APIs, neither one is consistent between Windows versions. For example... * Windows 2012 only supports a subset of the V2 API * Windows 2012 implements some V1 functions differently than 2008R2 * Windows 2016 broke compatibility with 2012R2 by replacing some classes Some of these differences are undocumented, too, which is just lovely. Most of these changes are relatively easy to handle, but the differences between 2008R2's and 2012's implementations of the V1 API result in libvirt code with a lot of conditionals containing obscure format strings in the 2008R2 blocks. Windows 2008R2's extended support ended January 14, 2020: https://docs.microsoft.com/en-us/lifecycle/products/windows-server-2008-r2 Windows 2012's mainstream support ended in 2018, but it still has extended support through October 10, 2023: https://docs.microsoft.com/en-us/lifecycle/products/windows-server-2012 Since 2008R2 is no longer supported by Microsoft, I propose removing support for it from libvirt. Thoughts?
