I have a Hyper-V 2012 R2 host with 8GB RAM. My guest VMs have 4096, 1024, and 768 MB of ram. When I try to add a new one with 256MB, it says it can't allocate enough RAM.
Is Hyper-V itself really taking up 25% of the memory? Thanks.

Yes and No. Emulation does take up some extra memory, some proportional to the memory used some not. Hyper V takes up 1G of memory and depending on how your graphics card is configured you may have some memory tied up with that.
Buy some more ram!
