[Qemu-devel] [PATCH v19 6/9] qmp/hmp: add set-vm-generation-id commands |
Date: |
Thu, 28 Jan 2016 11:54:28 +0100 |
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 324e6eaf-d1d1-4bf6-bf41-b9bb6c91fb87
Signed-off-by: Igor Mammedov <address@hidden>
---
v18:
- use new GuidInfo type introduced in previous patch and fix
argument to lowercase and corresponding example.
Eric Blake <address@hidden>
- s/if (errp != NULL)/if (errp)/
