[BUG] ovs process killed, coredump

[bobz965]

Kube-OVN Version

master

Kubernetes Version

1.31

Operation-system/Kernel Version

6.8 github ci

Description

ovs killed

Steps To Reproduce

github ci

Current Behavior

ovs process killed

Expected Behavior

ovs process running

[bobz965]

test arm env

the e2e failed, but the ovs pod is still running (not crashed)

[bobz965]

[bobz965]

先修复一下 arm 环境 lsp 类型 ovn eip 无法 ready 的问题： #4647

[bobz965]

@zcq98 目前基本确认在该步骤之后触发了 ovs pod 中，ovn-controller 进程的崩溃。

[bobz965]

已确认仅创建第二个vlan子网，没有在第二个子网中创建 lrp 类型的 eip， 不会导致 ovn-controller 崩溃

可以看到 extra 还没有和 vpc 连接

[bobz965]

一旦 extra vlan subnet 绑定到 vpc，创建出 lrp 就崩溃了 @zcq98
