It's probably based on the idea that SVHDX is implemented by the backing 
store, the (apparently-incorrect-on-this-point) spec says that if the 
data store doesn't support SVHDX, this error is to be returned, which 
lead us to get this create context to the VFS and generate the error 
from there.

But probably this error should not be generated.
