Subject Re: Problem with CLOUDSTACK-10240 (Cannot migrate local volume to shared storage)

Hi, Mike, Rafael:

Thanks for the clarification of what "managed storage" is and working on fixing the broken

    Another comment here: The part that is broken is if you try to let CloudStack pick the
primary storage on the destination side. That code no longer exists in 4.11.1.

        To follow up on this a bit: Yes, you should be able to migrate a VM and its storage
from one cluster to another today using non-managed (traditional) primary storage with XenServer
(both the source and destination primary storages would be cluster scoped). However, that
is one of the features that was broken in 4.11.1 that we are discussing in this thread.

            For a bit of info on what managed storage is, please take a look at this document:
            The short answer is that you can have zone-wide managed storage (for XenServer,
VMware, and KVM). However, there is no current zone-wide non-managed storage for XenServer.

                For Xen hypervisor, ACS does not support "zone-wide" primary storage yet.
Still, I can live migrate a VM with data disks between clusters with storage migration from
web GUI, today.  So, your statement below does not reflect current behavior of the code.
                           - If I want to migrate a VM across clusters, but if at least one
of its
                           volumes is placed in a cluster-wide managed storage, the migration
is not
                           allowed. Is that it?
                    [Mike] Correct
