What I had in mind was that S3 was supported but S4 was not. Amit confirmed that S4 is not supported in RHEL7, but: 1. We document, or at least imply, that both S3 and S4 are supported: 26.8. STARTING, SUSPENDING, RESUMING, SAVING AND RESTORING A GUEST VIRTUAL MACHINE https://url.corp.redhat.com/67b4d57 2. We advertise S4, and it just works: I'm able to suspend to disk from within the guest or by using virsh as documented in the virt guide 3. I wasn't able to suspend to S3, apparently because it's not being advertised to the guest IMPORTANT: For tests 2 and 3 I used a host running RHEL7.1 from a nightly build, so I'm not entirely sure I'd get the same results with RHEL7.0 stock. Either I'm really confused at this point or something needs fixing, but I need to know what's the intended behavior before going any further.
