VWorkspace 8.6.1 SQL requirements

I was going through the hardware and software requirements for vw 8.6.1 and it says vworkspace management database can be hosted on SQL 2012+. We don't have the ability to upgrade the SQL servers at this time. Is there a way to host it on SQL 2008 R2? Has anyone tried it?

Few more questions:

Can the broker role be installed on the Windows Servers 2012 R2 core? (Core edition without GUI)

Does vWorkspace Hyper-v Catalyst service support Hyper-V server? (Core edition without GUI)
