as far, as I can see VMotion is not possible/implemented with VI-Toolkit yet!?
That raises the question:"Which commands are selected to be integrated in VI-Toolkit" ... "why is no vm-vmotion availible (yet)"..."and who makes suggestions which commands are implemented"
Move-VM supports VMotion. It is of course necessary that the source and target hosts and the VM meet the criteria for VMotion. Assuming they do, something like this should work:
$target = Get-VMHost serverName
$vm = Get-VM vmName
Move-VM -VM $vm -Destination $target
If this is not working and it works through other means (e.g. through the Windows client), please post the set of commands you're trying and the relevant VC log and we'll follow up.

I've used this before in a non-vmotion environment and it worked great for what it was. Had to turn the VMs off of course.
