Merge pull request #1403 from mike-tutkowski/xs-snapshots
Taking fast and efficient volume snapshots with XenServer (and your storage
provider)A XenServer storage repository (SR) and virtual disk image (VDI) each
have UUIDs that are immutable.
This poses a problem for SAN snapshots, if you intend on mounting the
underlying snapshot SR alongside the source SR (duplicate UUIDs).
VMware has a solution for this called re-signaturing (so, in other words, the
snapshot UUIDs can be changed).
This PR only deals with the CloudStack side of things, but it works in concert
with a new XenServer storage manager created by CloudOps (this storage manager
enables re-signaturing of XenServer SR and VDI UUIDs).
I have written Marvin integration tests to go along with this, but cannot yet
check those into the CloudStack repo as they rely on SolidFire hardware.
If anyone would like to see these integration tests, please let me know.
