Start/Stop VM on Esxi by commands

Start/Stop command:

• List all VMs registered to this host (This reveals the Vmid needed for other commands)
  vim-cmd /vmsvc/getallvms
• Unregister a VM
  vim-cmd /vmsvc/unregister <Vmid>
• Register a VM
  vim-cmd /solo/register /path/to/file.vmx
• Get power state of a VM
  vim-cmd /vmsvc/power.getstate <Vimid>
• Power off a VM
  vim-cmd /vmsvc/power.off <Vmid>
• Power on a VM
  vim-cmd /vmsvc/power.on <Vmid>

Or Stop VM:

1. Open a console session where the esxcli tool is available, either in the ESXi Shell, the vSphere Management Assistant (vMA), or the location where the vSphere Command-Line Interface (vCLI) is installed.
2. Get a list of running virtual machines, identified by World ID, UUID, Display Name and path to the .vmx configuration file, using this command:
   
   esxcli vm process list
3. Power off one of the virtual machines from the list using this command:
   
   esxcli vm process kill --type=[soft,hard,force] --world-id=WorldNumber
   
   Note: Three power-off methods are available. Soft is the most graceful, hard performs an immediate shutdown, and force should be used as a last resort.
