[Qemu-devel] [PATCH] Extend qemu-ga's 'guest-info' command to expose flag 'success-response' |
Date: |
Wed, 18 Sep 2013 15:23:58 +0800 |
Now we have several qemu-ga commands not returning response on success.
It has been documented in qga/qapi-schema.json already. This patch exposes
the 'success-response' flag by extending 'guest-info' command. With this
change, the clients can handle the command response more flexibly.
