Date: |
Sun, 5 Feb 2017 01:12:02 -0800 |
From: Igor Mammedov <address@hidden>
Add set-vm-generation-id command to set Virtual Machine
Generation ID counter.
QMP command example:
{ "execute": "set-vm-generation-id",
"arguments": {
"guid": "324e6eaf-d1d1-4bf6-bf41-b9bb6c91fb87"
}
}
HMP command example:
set-vm-generation-id guid=324e6eaf-d1d1-4bf6-bf41-b9bb6c91fb87
