Bug description:
  There is QEMU/KVM and a Linux OS running inside the guest. 
  Inside the Linux guest a balloon consumes memory in accordance with 
  commands performed on the host side in QEMU and reports some statistics 
through memstat structure.
  For the Linux guest reported “free” value doesn’t describe the guest memory 
pressure at all.
  The provided patch set in Linux kernel extends the stat with available field.

  The problem is addressed in mainstream Linux with the following
  patchset:

  virtio_balloon: export 'available' memory to balloon statistics

  Add a new field, VIRTIO_BALLOON_S_AVAIL, to virtio_balloon memory
  statistics protocol, corresponding to 'Available' in /proc/meminfo.

  It indicates to the hypervisor how big the balloon can be inflated
  without pushing the guest system to swap.

  mm/page_alloc.c: calculate 'available' memory in a separate function

  Add a new field, VIRTIO_BALLOON_S_AVAIL, to virtio_balloon memory
  statistics protocol, corresponding to 'Available' in /proc/meminfo.

  It indicates to the hypervisor how big the balloon can be inflated
  without pushing the guest system to swap.  This metric would be very
  useful in VM orchestration software to improve memory management of
  different VMs under overcommit.

  This patch (of 2):

  Factor out calculation of the available memory counter into a separate
  exportable function, in order to be able to use it in other parts of the
  kernel.

  In particular, it appears a relevant metric to report to the hypervisor
  via virtio-balloon statistics interface (in a followup patch).

2016-06-14 Thread Kamal Mostafa 
This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
xenial' to 'verification-done-xenial'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Bug description:
  There is QEMU/KVM and a Linux OS running inside the guest. 
  Inside the Linux guest a balloon consumes memory in accordance with 
  commands performed on the host side in QEMU and reports some statistics 
through memstat structure.
  For the Linux guest reported “free” value doesn’t describe the guest memory 
pressure at all.
  The provided patch set in Linux kernel extends the stat with available field.

  virtio_balloon: export 'available' memory to balloon statistics

  Add a new field, VIRTIO_BALLOON_S_AVAIL, to virtio_balloon memory
  statistics protocol, corresponding to 'Available' in /proc/meminfo.

  It indicates to the hypervisor how big the balloon can be inflated
  without pushing the guest system to swap.

  mm/page_alloc.c: calculate 'available' memory in a separate function

  Add a new field, VIRTIO_BALLOON_S_AVAIL, to virtio_balloon memory
  statistics protocol, corresponding to 'Available' in /proc/meminfo.

  It indicates to the hypervisor how big the balloon can be inflated
  without pushing the guest system to swap.  This metric would be very
  useful in VM orchestration software to improve memory management of
  different VMs under overcommit.

  This patch (of 2):

  Factor out calculation of the available memory counter into a separate
  exportable function, in order to be able to use it in other parts of the
  kernel.

  In particular, it appears a relevant metric to report to the hypervisor
  via virtio-balloon statistics interface (in a followup patch).

  mm/page_alloc.c: calculate 'available' memory in a separate function

  Add a new field, VIRTIO_BALLOON_S_AVAIL, to virtio_balloon memory
  statistics protocol, corresponding to 'Available' in /proc/meminfo.

  It indicates to the hypervisor how big the balloon can be inflated
  without pushing the guest system to swap.  This metric would be very
  useful in VM orchestration software to improve memory management of
  different VMs under overcommit.

  This patch (of 2):

  Factor out calculation of the available memory counter into a separate
  exportable function, in order to be able to use it in other parts of the
  kernel.

  In particular, it appears a relevant metric to report to the hypervisor
  via virtio-balloon statistics interface (in a followup patch).

Title:
  Extended statistics from balloon for proper memory management

Status in linux package in Ubuntu:
  Fix Committed
Status in linux source package in Xenial:
  In Progress
Status in linux source package in Yakkety:
  Fix Committed

Bug description:
  There is QEMU/KVM and a Linux OS running inside the guest. 
  Inside the Linux guest a balloon consumes memory in accordance with 
  commands performed on the host side in QEMU and reports some statistics 
through memstat structure.
  For the Linux guest reported “free” value doesn’t describe the guest memory 
pressure at all.
  The provided patch set in Linux kernel extends the stat with available field.

  The problem is addressed in mainstream Linux with the following
  patchset:
