目前安装过4个版本的openv Switch，启动均会导致主机挂死：
1.基于openEuler22.03SP1 OLK内核编译的ovs的dpu-openEuler-20.03-LTS-SP1分支，且打了patch的版本
2.基于openEuler22.03SP1 OLK内核编译的ovs的dpu-openEuler-20.03-LTS-SP1分支，不打patch的版本，确认不是patch导致
3.基于openEuler22.03SP1 OLK内核编译的ovs的openEuler-22.03-LTS-SP3分支，发现最新版本启动也有问题
4.直接通过openEuler22.03SP1的源yum install openvswitch安装，发现原生版本也有启动问题

openv Switch启动会导致主机挂死，以下是/var/crash/下保存的日志：
