Qemu agent works on command line

[dea]

Hi, is possible send message in qemu agent throught the command line ?
I would enable/disable VSS in Windows VM from command line (like backup do)

Thanks

The socket will automatically be created here:

/var/run/qemu-server/<vmid>.qmp

and you can pipe commands in there according to http://wiki.qemu.org/Documentation/QMP

Perfect.
Pratically how can I send 'guest-fsfreeze-freeze' and 'guest-fsfreeze-thaw' to the VM ? OK I refer to the socket, but the qmp command ?

Very thanks

Wolfgang patched qm today to include a mechanism to do this directly from the command line via qm.

There a some qmp libraries for easier access, but without any library it would work with agent socket itself:

$ echo '{"execute":"guest-fsfreeze-freeze"}' | socat unix-connect:/var/run/qemu-server/<VMID>.qga -
