...a new command id. The obsolete pages for the previous start command can be detected by the id dismatching on the host. The id is added to the vq using an output buffer, and the free pages are added to the vq using input buffer. Here are some explainations about the added configuration registers: - host2guest_cmd: a register used by the host to send commands to the guest. - guest2host_cmd: written by the guest to ACK to the host about the commands that have been received. The host will clear the corresponding bits on the host2guest_cmd register. The guest also uses this register to send commands to the host...

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 array each time; and 2) free page block reporting: a new virtqueue to report guest free pages to the host. The second feature can be used to accelerate live migration of VMs. Here are some details: Live
