X-BeenThere: dev@dpdk.org X-Mailman-Version: 2.1.15 Precedence: list List-Id: DPDK patches and discussions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sat, 07 Oct 2017 16:59:16 -0000 Thanks Jianfeng for taking time to reply. please allow me to briefly explain why I want to run dpdk on xen. our system is based on dpdk, which means we use dpdk as packet receive/transmit engine, and with integrated dpdk virtio/vmxnet3 driver, our system can run on KVM/VMware platform . this year, we have plan to run our system on AWS cloud, but I found that AWS uses xen as its virtualization platform, and the bus-info of nic is vif-x (x could be 0,1,2...), the driver used in kernel is vif. this should be para-virtualized nic used on xen. I don't know which dpdk drvier can manage this pv nic. then I see xenvirt, I think this driver can did this job, like virtio can manage virtio nic which is used on kvm. unfortunately, after some study work, I run testpmd successfully on xen, but no packets received. with the informain got from you, I know It's need to run vhost_xen at dom0 so that xenvirt at domU can work. but for my case, I have no change to run vhost_xen at dom0, because I only can operate my own domU. for this case, If I want to run system which is based on dpdk at domU, what should I do? appreciate any idea or suggestion from you.
