  I think that this idea may have too many meanings to too many different people, making it difficult to see what people are actually asking for. I'm going to close this one out, but I've created three separate tickets, hopefully with a more clear description. Please remove your votes from this idea and cast them for one of the ideas below:

  * XCP: Allow disks of VMs to be live-migrated between SRs on the same host
  * Allow a VM with a locally-attached disk to live-migrate both VM and disk to another host
  * XCP: Allow live migration from OSS xen into XCP

  If what you voted for in this is neither of those, please add a comment here explaining in more detail what you have in mind (or create your own ticket).

  Thanks.

  And by move disks, I mean doing it live so could migrate to xcp with just a shutdown / startup (with disks kept in sync).

  George: both use cases would be useful. The first would allow a second SAN to be added and vm's storage migrated to new SAN (for expansion / load balancing / etc). The second case of live migrating a vm to a second location on a different SAN or local disks would be useful as well (say migrating a vm between datacentres).

  A third case, which I don't know if it is possible, but using storage motion to move disks from Xen to XCP. =)

  Alex, are you looking for moving the storage underneath a running VM, but not migrating the VM off the host it's on? Or are you looking at moving both the VM and the storage, say to another host with local storage?

  NB, I'm pretty sure that the most recent release of XCP (1.6) does have this feature, for those who don't want to wait. :-)
