Situation description:
After the cluster is successfully built for the first time, the host can ping the virtual machine, but suddenly it cannot be pinged after restarting.
Solution:
Wmnet0 externally connected network card designation error
This situation is more common. If the wrong network card is specified, it will cause the host and the virtual machine to fail to ping each other. Bridge connection can choose "automatic" , there will also be the situation that ping is not possible , then you need to specify the network card used. The specified network card is generally the network card used by the host on the same network as the virtual machine.
