Eelco Dolstra e2dbfbdcf4 * Use writeback caching for virtual disks instead of writethrough
caching.  This makes a huge performance difference (e.g. from 4 MB/s
  `dd' throughput to 140 MB/s on the Hydra machines).  As the QEMU
  manual says: "Some block drivers perform badly with
  ‘cache=writethrough’, most notably, qcow2."
