A big interest for me was :

Q7: Is Hyper-V Dynamic Memory supported for SQL Server?

A7: Hyper-V Dynamic Memory is fully supported with SQL Server. Only SQL Server versions and editions that support Hot Add Memory (Enterprise and Datacenter) can see memory that is added by using Hyper-V Dynamic Memory. SQL Server 2012 Standard edition also recognizes Hot Add memory when running in a virtual environment. SQL Server versions that do not support Hot Add Memory are still supported. But these versions will detect only the memory that is present in the operating system when SQL Server starts.

So if the VM was setup with dynamic memory allocation: for example 4GB of initial memory with a maximum of 28GB, this is not OK for SQL Server Standard Edition. According to the above Microsoft notice our SQL Server is unable to see more than the initial 4GB.
