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) free_page_vq: 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 migration needs to

Add a new feature, VIRTIO_BALLOON_F_SG, which enables to transfer a chunk of ballooned (i.e. inflated/deflated) pages using scatter-gather lists to the host. The implementation of the previous virtio-balloon is not very efficient, because the balloon pages are transferred to the host one by one. Here is the breakdown of the time in percentage spent on each step of the balloon inflating process

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

Add a new vq, cmdq, to handle requests between the device and driver. This patch implements two commands sent from the device and handled in the driver. 1) VIRTIO_BALLOON_CMDQ_REPORT_STATS: this command is used to report the guest memory statistics to the host. The stats_vq mechanism is not used when the cmdq mechanism is enabled. 2) VIRTIO_BALLOON_CMDQ_REPORT_UNUSED_PAGES: this command is used
