So, in my case, both the source and target datastores are cluster-scoped
primary storage in CloudStack (not zone wide). Would that matter? For
XenServer, that cluster-scoped configuration (but using storage repositories,
of course) works.

It looks like a bug. For vmware, moving root volume with migrateVolume with
livemigrate=true for zone-wide PS works just fine for us. In the background, it
uses StoragevMotion. From another angle 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.

Thanks, Simon
I wonder if we support that in CloudStack.

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

Slight typo:

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.
