default cni network does not support multi-node

[silenceshell]

If the network is default cni, I think we cannot access vm's IIP from other computers as the IP is like 172.18.0.0/16.

@silenceshell I think this is not true for a multi-host CNI like Weave Net.
Weave Net, for example, offers IPs in the 10.32.0.0/16 space and accessible across nodes.

yeah, weave is an-third-party-cni-plugin, and supports multi-node, while the default cni is bridge and not support multi-node.
