So both VM's are still sitting at the same memory usage according to hyper-v.
Memory demand hasn't seemed to budge either.
I tried this on a 15.10 box we had, and got very different results. I
logged in (Server needs a GUI for some tools) and memory went from 2gb
to 6gb. I did a few things, did a
This machine didn't have any impact, but the other one dropped about 1g
of ram when I did that, less than should have been reclaimed, but some
reclamation at least.

My apologies for so many separate comments, I'll try to keep the noise
down.
I should add that these boxes run redis, and the amount of data in redis
is fairly static. It's a devtest environment. Memory demand peaks at
boot and then falls off to a constant usage. So it's safe to assume that
the
This is the first time i've seen "free" drop down low as it should, but
the memory still hasn't been reclaimed by hyper-v. This particular VM
has been up 19 days. am I wrong in thinking that dynamic mem should have
scaled back to maybe... 2.2-ish GB? Roughly?
I tried looking at hv_balloon.c, but
Here's another screenshot from a different VM, same thing as previous
screenshot.
Demand should be roughly 3.6ish, but instead it's 7ish.
This box has been running for 7 days, I think this is the machine from
the original screenshot.

This bug is causing some serious issues for us with the 16.04 rollout.
We oversubscribe which is admittedly our problem, and our 16.04 VM's
spike to 8gb during boot, but then settle at a reasonable 2gb, but the
VM continues to hog 8gb to itself. We have 5 total, so that's a grand
total of 30GB
