Re: Cannot migrate VMware VM with root disk to host in different cluster (CloudStack 4.10)

[Tutkowski, Mike]

This looks a little suspicious to me (in VmwareResource before we call 
VirtualMachineMO.changeDatastore):

                morDsAtTarget = 
HypervisorHostHelper.findDatastoreWithBackwardsCompatibility(tgtHyperHost, 
filerTo.getUuid());
                morDsAtSource = 
HypervisorHostHelper.findDatastoreWithBackwardsCompatibility(srcHyperHost, 
filerTo.getUuid());
                if (morDsAtTarget == null) {
                    String msg = "Unable to find the target datastore: " + 
filerTo.getUuid() + " on target host: " + tgtHyperHost.getHyperHostName() + " 
to execute MigrateWithStorageCommand";
                    s_logger.error(msg);
                    throw new Exception(msg);
                }

We use filerTo.getUuid() when trying to get a pointer to both the target and 
source datastores. Since filerTo.getUuid() has the UUID for the target 
datastore, that works for morDsAtTarget, but morDsAtSource ends up being null.

For some reason, we only check if morDsAtTarget is null (I’m not sure why we 
don’t check if morDsAtSource is null, too).

    Hi,
    
    The CloudStack API that the GUI is invoking is 
migrateVirtualMachineWithVolume (which is expected since I’m asking to migrate 
a VM from a host in one cluster to a host in another cluster).
    
    A MigrateWithStorageCommand is sent to VmwareResource, which eventually 
calls VirtualMachineMO.changeDatastore.
    
        public boolean changeDatastore(VirtualMachineRelocateSpec relocateSpec) 
throws Exception {
            ManagedObjectReference morTask = 
_context.getVimClient().getService().relocateVMTask(_mor, relocateSpec, 
VirtualMachineMovePriority.DEFAULT_PRIORITY);
            boolean result = _context.getVimClient().waitForTask(morTask);
            if (result) {
                _context.waitForTaskProgressDone(morTask);
                return true;
            } else {
                s_logger.error("VMware RelocateVM_Task to change datastore 
failed due to " + TaskMO.getTaskFailureInfo(_context, morTask));
            }
            return false;
        }
    
    The parameter, VirtualMachineRelocateSpec, looks like this:
    
    http://imgur.com/a/vtKcq (datastore-66 is the target datastore)
    
    The following error message is returned:
    
    Required property datastore is missing from data object of type

    Thoughts?

        Can you trace which API call being used and what parameters were 
specified? migrateVirtualMachineWithVolumeAttempts vs migrateVirtualMachine
