如果想让pve主机上网，加一条默认路由即可
ip route add default via 192.168.3.254
或
ip route add default via 192.168.1.254
虚拟机配网关就能上网
pve主机其实什么地址也不用配，但是为了管理它，所以配了两个地址，一个管理地址192.168.1.53，另外一个存储地址192.168.3.53，这两个地址在防火墙上控制它们能不能上网即可，分内网通信与外网通信，虚拟机需要外网通信。存储网络与管理网络不需要上网。
在debian中如果永久添加静态路由，就要在bond0.7上配ip，并加路由

=================================================
EtherChannel支持基于2层MAC，3层IP，4层端口号的源/目的的负载均衡，高效地使用现有链路
链路聚合技术亦称主干技术（Trunking）或捆绑技术（Bonding）
强烈建议把Proxmox的集群网络、存储网络、虚拟机通信网络分开。网络规划上为这三者分别划分独立网段
