Any installs must be the latest edition (currently 2016) as 365 does not carry any downgrade rights (ths is not just RDS environments, this is for any 365 install).
There are no changes from standard virtualisation licensing - same rules apply:
Have a control on your environment - those who "could access" need a license, so ensure policy/controls are in place to manage user access (or if for all, then this is okay).
RDS CALs - determine between Per User and Per Device - VDI is normally assumed as Per User which aligns to 365 licensing
If your VDI is set on a Windows Server Infrastructure you will need Windows RDS CAL (and a Windows CAL)
If your VDI is set on a non-windows infrastructure you don't need an RDS CAL for access (although may require it for other programmes, so check!)
There were initially technical issues in deployment of Office ProPlus 365 in a Citrix environment which led to Microsoft offering a shortterm concession to deploy Office VL instead of 365 version - however this is all now resolved and concession not applicable.
