Hi,
This series is a respin of automatic ballooning support I started
working on last year. Patch 2/2 contains all relevant technical
details and performance measurements results.
This is in RFC state because it's a work in progress.
Here's some information if you want to try automatic ballooning:
1. You'll need 3.9+ for the host kernel
2. Apply this series for the guest kernel
3. Grab the QEMU bits from:
git://repo.or.cz/qemu/qmp-unstable.git balloon/auto-ballooning/memcg/rfc
4. Enable the balloon device in qemu with:
-device virtio-balloon-pci,auto-balloon=true
5. Balloon the guest memory down, say from 1G to 256MB
6. Generate some pressure in the guest, say a kernel build with -j16
Any feedback is appreciated!
