[pve-devel] [PATCH 2/2] now if the QMP command starts with guest-+ , it will bind dynamicly to the VMID.qga socket. To test the function vmtime is implemented which return the vm UNIX Time.

>>Ah, OK. Or we can save the state of the last command into a temp file, so that we can avoid the delay? 

I'm not sure, because It's possible that qga daemon can be stopped, or crash, ....

Ah, OK. Or we can save the state of the last command into a temp file, 
so that we can avoid the delay? 

if (last_command_was_successful()) { 
run_qmp_command() 
} else { 
test_conn_with_small_timeout() 
run_qmp_command() 
}
