Title:
Hyper-V Memory Ballooning re-broken in 16.04
Status in linux package in Ubuntu:
Incomplete
Bug description:
Regression: #1294283 fixed memory ballooning in Hyper-V in 14.04, but
the bug has returned in 16.04.
Steps to reproduce:
1. Create Gen2 Hyper-V VM
2. Install Ubuntu 16.04
3. modprobe hv_balloon
Memory usage according to Hyper-V Manager will not change
This has been reproduced on 2 fresh Ubuntu Server 16.04 instances.
I installed linux-generic-xenial on a 14.04 instance, rebooted,
modprobe'd hv_balloon and memory usage in Hyper-V Manager reduced to
the correct level.
