Hello, There's been a flurry of activity around indrect goto recently. For anyone interested, here's a document explaining the curent design: http://nondot.org/sabre/LLVMNotes/IndirectGoto.txt Dan

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 using sgs, 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.
