  • Thread-topic: throttling logs messages from qemu

I see that in 3.4.x, throttling has been changed from a file in /etc to
a xenstore entry, as per the following code:

    throttling = xenstore_vm_read(domid, "log-throttling", &len);
    if (throttling != NULL) {
        throttling_disabled = (throttling[0] - '0');
        free(throttling);
    }

A bit of searching tells me that the full path of the key is
/vm/<uuid>/log-throttling, but it appears to be read at boot. How can I
get it written in there in time?

James
