[Qemu-devel] [PATCH v17 6/9] qmp/hmp: add set-vm-generation-id commands |
Date: |
Tue, 19 Jan 2016 14:06:26 +0100 |
Add set-vm-generation-id command to set Virtual Machine
Generation ID counter.
QMP command example:
{ "execute": "set-vm-generation-id",
"arguments": {
"uuid": "324e6eaf-d1d1-4bf6-bf41-b9bb6c91fb87"
}
}
HMP command example:
set-vm-generation-id 324e6eaf-d1d1-4bf6-bf41-b9bb6c91fb87
