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: commit 5057dcd0f1aaad57e07e728ba20a99e205c6b9de Author: Igor Redko Date: Thu Mar 17 15:09:34 2016 -0700 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. 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). Signed-off-by: Igor Redko Signed-off-by: Denis V.
