Thanks. In both VMs, it looks like the buff/cached memory dropped by 2GB. After some time, did the Hyper-V host eventually reclaim this memory? Can you check if the Hyper-V host's assigned memory also drops after some time?
Also, can you tell us if you tried this on an older build where it doesn't repro? -- 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
