Hi,


I needed to run an external program in a guest machine. Once this must be
triggered by the host, I first thought in qemu-ga.
Is that possible? In QEMU help page and in the code I couldn't find such
capability.
So Im thinking In to implement a new GA QMP command that can run generic
programs in the guest. It would be receive/return something like this:

{"execute":"execvp",
"arguments":{"command":"/bin/ls","cmdargs":"-la","timeout":20}}
{"return": {"status": "0", "stdout": "aGVsbG8gd29ybGQhCg==", "stderr": ""}}

Any thoughts/ideas about this?

Kind Regards,
Erlon
