Thanks - you are definitely onto something. lsmod | grep hv_ shows hv_balloon on the low memory machine but not on the other - so the balloon module is loaded on one and not the other. And the behaviour looks very much like this description.

Not sure what the equivalent to vmware-toolbox-cmd is on Hyper V though.

@assylias I know, sorry. I looked myself while writing this answer and came up empty. However, if you write a program that quickly allocates a lot of memory, that may convince the hypervisor that your VM needs the resources. Similar to disk cache eviction test case, but different root cause.

You can unset the dynamic ram feature in Hyper-V to solve this issue.

I don't really see the solution here I'm afraid.
