For a bit of info on what managed storage is, please take a look at this document:
https://www.dropbox.com/s/wwz2bjpra9ykk5w/SolidFire%20in%20CloudStack.docx?dl=0 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
