[PATCH v11 0/6] Virtio-balloon Enhancement
This patch series enhances the existing virtio-balloon with the following new
features:
1) fast ballooning: transfer ballooned pages between the guest and host in
chunks, instead of one by one; and
2) cmdq: a new virtqueue to send commands between the device and driver.
Currently, it supports commands to report memory stats (replace the old statq
mechanism) and report guest unused pages.
