如果想讓pve主機上網，加一條默認路由即可
ip route add default via 192.168.3.254
或
ip route add default via 192.168.1.254
虛擬機配網關就能上網
pve主機其實什么地址也不用配，但是為了管理它，所以配了兩個地址，一個管理地址192.168.1.53，另外一個存儲地址192.168.3.53，這兩個地址在防火牆上控制它們能不能上網即可，分內網通信與外網通信，虛擬機需要外網通信。存儲網絡與管理網絡不需要上網。
在debian中如果永久添加靜態路由，就要在bond0.7上配ip，並加路由

=================================================
EtherChannel支持基於2層MAC，3層IP，4層端口號的源/目的的負載均衡，高效地使用現有鏈路
鏈路聚合技術亦稱主干技術（Trunking）或捆綁技術（Bonding）
強烈建議把Proxmox的集群網絡、存儲網絡、虛擬機通信網絡分開。網絡規划上為這三者分別划分獨立網段
