Hyper-V itself will install, but doing so would be pointless since
Hyper-V itself is so lightweight.
You might want to store your virtual hard drives on an SSD though.
In this context, TRIM won't really matter. I'd guess that R2 will
support TRIM natively similar to W7, but I'm not aware of any mechanism
that would support TRIM within a guest and pass TRIM out to the host, so
the useful of TRIM will be drastically reduced. In other words, plan
for no TRIM support and look for a controller (like Crucial's latest
firmware) that supports garbage collection as an alternative to TRIM.
Another issue is cluster alignment, aligning a physical partition
correctly should happen automatically but guests may well not end up
aligned to the physical cluster boundaries of the SSD, incurring
significant write penalties.
