I think I should open a blocker for this for 4.10. Perhaps one of our VMware
people can take a look. It sounds like it’s a critical issue.

OK, yeah, it does.
The source host has access to the source datastore and the destination host
has access to the destination datastore.
The source host does not have access to the destination datastore nor does
the destination host have access to the source datastore.
I've been focusing on doing this with a source and a host datastore that
are both either NFS or iSCSI (but I think you should be able to go NFS to iSCSI
or vice versa, as well).

MigrateVirtualMachine works also perfectly fine. I know for a fact that vmware
supports moving from host to host and storage to storage at the same time so it
seems to be a bug in migrateVirtualMachineWithVolume implementation. vSphere
standard license is enough for both regular and storage vMotion.

>>> Yes, Mike. But that’s the case with versions less than 5.1 only. In
vSphere 5.1 and later, vMotion does not require environments with shared
storage. This is useful for performing cross-cluster migrations, when the
target cluster machines might not have access to the source cluster's storage.
