The Virtual Machine high availability configuration allows the Virtual Machine System to provide 24x7 services. When a problem occurs on the host machine where the virtual machine is located, the Failover function automatically migrates the virtual machine to other nodes in the cluster, in this process, the virtual machine service continues, and two ping packets are dropped at most. The following describes
