----------------------------------------------------------------------

I noticed this also happens in this situation:

I have two XenServer clusters, each with its own NFS SR.

In the one cluster, I have a VM. Its root disk is housed on the one and only 
NFS SR of that cluster.

The GUI tells me I can migrate the VM to a host in the other cluster, but that 
it will require storage migration. I am OK with this and start the migration 
action.

The GUI sends a migrateVirtualMachine API command instead of a 
migrateVirtualMachineWithVolume API command to the management server and the 
process fails. It does fail gracefully (nothing seems to be left in a bad 
state).

As an FYI, though, even if the GUI were calling the correct API command in this 
particular instance, it would fail due to this issue:

>          Components: UI
>    Affects Versions: 4.11.0.0

>
> I have a VM whose root disk in on zone-wide, managed storage.
> When I go to migrate the VM to a host in another cluster, the GUI correctly 
> points out that to migrate the VM to the desired host that storage migration 
> will be required.
> Since I am good with both the VM and its disk being migrated, I initiate the 
> action.
> The GUI ends up invoking the migrateVirtualMachine API command instead of the 
> migrateVirtualMachineWithVolume API command, which causes the process to 
> fail. The process does fail gracefully (nothing seems to be left in a bad 
> state).
> If I invoke the migrateVirtualMachineWithVolume API command from CloudMonkey 
> and pass in the necessary parameters, the migration is successful.
> I know this used to work from the GUI at some point in 4.10 development 
> because I recorded a video demonstrating this feature as executed from the 
> GUI:
