I was debugging a case where 200 snapshots of a disk would result in a
VERY long reconnect time after libvirtd restart when debug logging was

I've figured out that qemu responds with 9MiB of json after calling
"query-named-block-nodes" and this resulted in > 26 GiB of libvirtd
debug log just to process the message.

I'll report the qemu flaw separately.

  util: probe: Add quiet versions of the "PROBE" macro
  qemu: monitor: Decrease logging verbosity
