Re: [Xen-devel] [dpdk-dev] Can xenvirt pmd work in xen guest (aka DomU) without xen-vhost in Dom0 ?

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.

Hi Jianfeng,
Thank you for replying, I appreciate so much for this.
we are trying to run our dpdk application on AWS cloud which use xen platform.
for this case, what should I do to support AWS cloud ?
Is there any way to do this ?

Sorry, I don't have knowledge to answer this question as I don't know what kind of net devices in AWS cloud.

Thanks,
