虚拟网卡会导致rac的安装前检查不通过

– 检查状态

[root@racdb01 ~]# virsh net-listName                 State      Autostart     Persistent--------------------------------------------------default              active     yes           yes

– destroy

[root@racdb01 ~]# virsh net-destroy defaultNetwork default destroyed

– undefine

[root@racdb01 ~]# virsh net-undefine defaultNetwork default has been undefined

– reboot

[root@racdb01 ~]# service libvirtd restart Stopping libvirtd daemon:                                  [  OK  ]Starting libvirtd daemon:                                  [  OK  ]

再次确认
