Without ivshmem, throuput between VMs is largely decreased. So we are not so happy if ivshmem is obsoleted. As you mentioned, we can use v16.07 but it's unwelcome situation for us and our possible users cannot gain of improvements from future version of DPDK. I'm appreciated if you kindly keep ivshmem to be maintained. Or, is there any idea for high-performance inter-VM communication as ivshmem?
