绑定接口作为从设备时，桥接模式下KVM虚拟机无法联网的问题求助

各位好，我现在碰到个棘手的问题：当KVM虚拟机的网络桥接配置里，用了绑定接口作为从设备时，我完全没法通过网络访问这个KVM虚拟机了，折腾好一阵都没头绪，来这儿求助大家！

先说说我是怎么创建绑定接口bond0的：

sudo nmcli connection add type bond con-name bond0 ifname bond0 bond.options "mode=802.3ad"
sudo nmcli connection add type ethernet slave-type bond con-name bond0-port1 ifname eno1np0 master bond0
sudo nmcli connection add type ethernet slave-type bond con-name bond0-port2 ifname eno2np1 master bond0

另外我把/proc/net/bonding/bond0的输出信息贴出来，供大家参考：

Bonding Mode: IEEE 802.3ad Dynamic link aggregation
Transmit Hash Policy: layer2 (0)
MII Status: up
MII Polling Interval (ms): 100
Up Delay (ms): 0
Down Delay (ms): 0
Peer Notification Delay (ms): 0

802.3ad info
LACP active: on
LACP rate: slow
Min links: 0
Aggregator selection policy (ad_select): stable

有没有大佬能帮忙分析下问题可能出在哪？或者给点排查的方向也行，万分感谢！
