important to turn off the "lockdown mode" when SSH login is activated, in fact, if you close the Lockdown lock mode directly, you can log into the Web management interface of the ESXI host client directly.After that, you can log in to the ESXi host via SSH and use the relevant commands to start or shut down the virtual machine. It can also be managed by logging into the Web management interface of the ESXi
