Review comment:
Hi @sureshanaparti, may I suggest here to get the VMSnapshotStrategy
instead of checking which is the storage pool type? If it's an instance of
DefaultVMSnapshotStrategy to get into the statement. In this case, the other
storage plugins could implement their own VM snapshot strategy, without
checking here which is the storage pool type. I saw that Solidfire's API has a
group snapshot (maybe and others have it). We at StorPool also have this
functionality (but for now we have a workaround for this). I guess someday it
will be easier for the plugins to adopt this functionality
