[PATCH v8 3/3] qmp: add new qmp display-reload |
Date: |
Tue, 16 Mar 2021 15:58:45 +0800 |
This patch provides a new qmp to reload display configuration
without restart VM, but only reloading the vnc tls certificates
is implemented.
Example:
{"execute": "display-reload", "arguments":{"type": "vnc", "tls-certs": true}}
