Yes, commands are executed asynchronously. guest-exec kicks them off and
returns a handle. guest-exec-status can be called later with that handle
to check on the status of the command. If the command has completed,
guest-exec-status will report the return status, along with stdout/stderr
if capture mode was enabled. Multiple commands can be issued/running at
any one time.
The documentation in qemu.git/qga/qapi-schema.json has more exact details.
