[Qemu-devel] [PATCH 3/6] qemu-ga: guest-shutdown: don't emit a success response |
Date: |

Today, qemu-ga may not be able to emit a success response when
guest-shutdown completes. This happens because the VM may vanish
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-shutdown to never
emit a success response and suggests in the documentation what
clients could do to check for success.
