Does Google Compute Engine offer SR-IOV (Single Root I/O Virtualization)?
Currently Google Compute Engine does not offer SR-IOV. That said, SR-IOV is not strictly necessary to take advantage of Scylla's architecture. GCE offers multi-queue networking and it is possible to directly user-mode assign the virtio-net queues using Intel's DPDK. This should allow our virtio-net NIC to work with Scylla, although at least at one point DPDK made certain qemu specific assumptions

SR-IOV Networking in Xen: Architecture, Design and Implementation Yaozu Dong, Zhao Yu and Greg Rose Abstract. SR-IOV capable network devices offer the benefits of direct I/O throughput and reduced CPU utilization while greatly increasing the scalability and sharing capabilities of the device. SR-IOV allows the benefits of the paravirtualized driver’s throughput increase and additional CPU usage r
