How to resolve 'Virtual machine connection has been lost' error?

When encountering the "VirtualMachineconnectionhasbeenlost" error, you should avoid blind restarting, but follow the following steps to check: 1. Check whether the network connection is normal, including local and remote networks, firewall rules, port opening status and intermediate proxy links; 2. Confirm whether the virtual machine status is running normally, check the management platform status and check the system log or console screenshot; 3. Check whether the remote connection services such as RDP or SSH are running, and restart the related services through the serial console if necessary; 4. Check resource overload or configuration issues, check CPU, memory, and disk usage, and perform corresponding cleaning or expansion operations. Check them one by one in the above order, and most connection loss problems can be solved.
