Multiple Windows VMs, all of them with identical software installed (they're clones in fact) that I have to run for administrative+licensing reasons, give me a headache storage-wise. KVM on Linux runs great but ext4 does not provide any features re de-duplication.

There's LessFS and it seems nice but is anyone running it in production without major problems?

If not LessFS, then the question is: is there production-ready disk de-duplication filesystem that I could use for KVM?

Look into ZFS on Linux. That will deduplicate all day long...

You'll need a lot of RAM and may find that this may not be worth the effort (you could have sized appropriately for your needs), but it does work.
