The hv_balloon driver hasn't changed between 15.10 and 16.04, so there shouldn't be any difference in the way the driver reports demand to Hyper-V.
To provide a further breakdown of the memory usage, can you show the output of "cat /proc/meminfo"? Might help to compare this info between 16.04 and 15.10. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1584597 Title: Hyper-V Memory Ballooning re-broken in 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1584597/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
