VMware KB1003797 – Unable to migrate: Virtual machine is configured to use a device that prevents migration
There seems to be a lot of confusion about vMotion and bus-shared VMDKs. For the record, and from VMware, it is not recommended nor supported to vMotion your VM between ESX Hosts when using either Virtual or Physical mode bus-sharing.
I know there are plenty that will disagree and have found ways of doing it, but within our environments for our MSCS clusters using Physical mode, we disable DRS and only Cold vMotion once the resources of the cluster have been moved off the Node and the VM is Powered Off.
