[XCP] RFC: cross-host VDI.copy

From Dave Scott – http://lists.xensource.com/archives/html/xen-api/2010-08/msg00031.html

I’ve written a proposal on the wiki for “Cross-host VDI.copy” i.e. the ability to copy VDIs (disks) and therefore VMs between storage repositories on separate XCP hosts:

http://wiki.xensource.com/xenwiki/Cross-host_VDI.copy

Currently XCP only supports copying disks between Storage Repositories where at least one host in the pool can see both bits of storage at once i.e. from shared -> local; local -> shared; and local -> local on the same host. This adds generic support for local -> local disk copying by using the existing “Raw VDI import” functionality.

This ought to be especially useful for people who have pools but who don’t have shared storage.

Comments welcome.
