In both screenshots, it appears that the "buff/cache" value is very high.
Perhaps the balloon driver is reporting the "buff/cache" as in use to the host. Can you try running following commands to flush write buffers and free page cache? 1) sync 2) echo 3 > /proc/sys/vm/drop_caches After running the above, do you see that the "buff/cache" value decreases and does this result in the memory being reclaimed by Hyper-V? -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
