OK - when I scrolled down to the changes in qemu_command.c/
qemuBuildRNGDeviceArgs(), I saw:
+ if (dev->rate > 0) {
+ virBufferAsprintf(&buf, ",max-bytes=%u", dev->rate);
+ if (dev->period)
+ virBufferAsprintf(&buf, ",period=%u", dev->period);
+ else
+ virBufferAddLit(&buf, ",period=1000");
+ }
+
Hence the reason I asked...
