How to access virtual machine host information

[ThreepE0]

Trying to figure out how to get information about the host for a given virtual machine.

Tried:
$virtualMachines = $vhost->findAllManagedObjects('VirtualMachine', array('parent', 'name', 'guest'));
but accessing $vm->parent or $vm->host or $vm->hostSystem doesn't get me to the eSXI machine running the vm.

Tried:
$hosts = $vhost->findAllManagedObjects('HostSystem', array('name')); foreach($hosts as $host){ echo '<h1>'.$host->name.'</h1>'; var_dump($host->findAllManagedObjects('VirtualMachine', array('parent', 'name', 'guest')); }
But it doesn't look like running 'findAllManagedObjects' on the host is supported
