From: Luiz Capitulino <lcapitul...@redhat.com> Today, qemu-ga may not be able to emit a success response when guest-suspend-ram completes. This happens because the VM may suspend before qemu-ga is able to emit a response.
This semantic is a bit confusing, as it's not clear for clients if they should wait for a response or how they should check for success. This commit solves that problem by changing guest-suspend-ram to never emit a success response and suggests in the documentation what clients should do to check for success.
