Virtio hardware accelerators and other news
summary
Virtio gets a hardware-oriented update: Virtio 1.1 is in final review with ring simplifications and stronger memory ordering flags to make real devices feasible, and a PCI/FPGA FPGA Virtio accelerator is announced for Q1 2019 that supports full Virtio offload and live migration. Software pieces exist: DPDK patches landed, QEMU adds a vhost-vfio client and userspace backends, and kernel-side vhost-mdev support is under review so hardware control vs data path can be separated.
