5:08 p.m.
The two new APIs are rather trivial; based on bits and pieces of
other existing APIs. I chose to blindly return 0 for HasMetadata,
since we already do that for other APIs like domainIsPersistent.
* src/esx/esx_driver.c (esxDomainSnapshotIsCurrent)
(esxDomainSnapshotHasMetadata): New functions.
* src/vbox/vbox_tmpl.c (vboxDomainSnapshotIsCurrent)
(vboxDomainSnapshotHasMetadata): Likewise.

This version avoids existence checks. I don't like it, but it is
shorter, so it's worth posting.
