[Qemu-devel] [PATCH 4/8] QMP: Introduce qmp_switch_mode command |
Date: |
Thu, 28 Jan 2010 11:42:56 -0200 |
It will be used to switch between "handshake" and "operational"
modes. Currently it doesn't have any practical effect, as
mode-oriented support is not enforced yet.
Usage example:
{ "execute": "qmp_switch_mode", "arguments": { "mode": "operational" } }
