vMotion appears to have stalled for one vm

Hello,

We are running vSphere 5.1 / ESXi 5.1

I've been moving machines around various datastores and hosts today both using DRS and SDRS and manual migrations. All machines apart from one have sucessfully migrated and so I've decided to try and cancel the migration of this machine.

Except I can't because the option is greyed out. Is there a powercli or SSH command I can run that will do one of the following:

1. Tell me which datastore and / or host the machine is migrating to.

2. Cancel the migration entirely.

Bear in mind this is an production server with many users logged in during the working day. I will attempt to power off the machine later on this evening using these guides as reference:

But obviously if I can do something now then that would be the better choice.

Thanks
