IIRC, CloudStack supports this. I am testing this out in my 4.10 environment,
will update shortly.

Mike,
It is possible to do this on vcenter, but it requires a special license
I believe.
Here's the info on it :

Subject: Re: Cannot migrate VMware VM with root disk to host in
different cluster (CloudStack 4.10)
This is interesting:
If I shut the VM down and then migrate its root disk to storage in the
other cluster, then start up the VM, the VM gets started up correctly (running
on the new host using the other datastore).
Perhaps you simply cannot live migrate a VM and its storage from one
cluster to another with VMware? This works for XenServer and I probably just
assumed it would work in VMware, but maybe it doesn’t?
The reason I’m asking now is because I’m investigating the support of
cross-cluster migration of a VM that uses managed storage. This works for
XenServer as of 4.9 and I was looking to implement similar functionality for
VMware.

Another piece of info:
I tried this same VM + storage migration using NFS for both
datastores instead of iSCSI for both datastores and it failed with the same
error message:

Slight typo:
Both ESXi hosts are version 5.5 and both clusters are within
the same VMware datastore.
Should be (datastore changed to datacenter):
Both ESXi hosts are version 5.5 and both clusters are within
the same VMware datacenter.

A little update here:
In the debugger, I made sure we asked for the correct
source datastore (I edited the UUID we were using for the source datastore).
When VirtualMachineMO.changeDatastore is later invoked
having the proper source and target datastores, I now see this error message:
Virtual disk 'Hard disk 1' is not accessible on the host:
Unable to access file [SIOC-1]
Both ESXi hosts are version 5.5 and both clusters are
within the same VMware datastore.
The source datastore and the target datastore are both
using iSCSI.

>> 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.
