Hi:
May I ask the reason for using raw socket for vhost? It was not a
common setup with little care in the past few years. And it was slow
since it lacks some recent improvements. Can it be replaced with e.g
macvtap?
Hi Jason,
Apologize for late response. We are in container environment, in which
case veth is used mostly. Either tap or macvtap cannot be put into an
isolated netns.
I think it can? See 17af2bce88d31e65ed73d638bb752d2e13c66ced.
Another thing could be macvlan as the backend of vhost, which is not
supported either. So unfortunately, improving raw socket is the only
choice I suppose.
Btw, you can setup macvtap on top of veth. Does this help?
Thanks
Thanks,
Jianfeng
