Listing configured Virtual Machines:

$ vmware-cmd -l
/var/lib/vmware/Virtual Machines/Server-01/Windows 2000 Server.vmx
/var/lib/vmware/Virtual Machines/Server-01/RedHat5.vmx 

Get the state of a Virtual Machine:

$ vmware-cmd "/var/lib/vmware/Virtual Machines/Server-01/RedHat5.vmx" getstate

Start (or resume) a Virtual Machine:

$ vmware-cmd "/var/lib/vmware/Virtual Machines/Server-01/RedHat5.vmx" start

Stop a Virtual Machine:

$ vmware-cmd "/var/lib/vmware/Virtual Machines/Server-01/RedHat5.vmx" stop

Reset a Virtual Machine:

$ vmware-cmd "/var/lib/vmware/Virtual Machines/Server-01/RedHat5.vmx" reset
