To list the virtual machines installed on a VMWare ESXi server, loging to the server via ssh and enter the following command:

~ # esxcli vms vm list
World ID: 9375350
Process ID: 0
VMX Cartel ID: 9375349
UUID: 56 4d 7e ca e0 c8 15 17-53 2e 21 de 2f 57 6b f0
Display Name: VMDC1
Config File: /vmfs/volumes/4cd70f88-eac98d60-3346-b8ac6f907086/VMDC1/VMDC1.vmx

There are several other options to the esxcli command, but another potentially useful option is the following command used to kill a hung VM:

~ # esxcli vms vm kill
~ # esxcli vms vm kill –type soft|hard|force –world-id World ID
