Hi,
After having debugged a hibernation BZ reported by QE, I got confused
about the support status of suspend/hibernate in RHEL7.
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

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.
