Following on from my command in the first patch, we should be doing

  for (i = 0 ; i < vm->def->ndisks ; i++) {
      if (vm->def->disks[i].rawio)
         virCommandAllowCap(cmd, CAP_SYS_RAWIO);
  }

And, in qemuDomainObjCheckDiskTaint() you need to add code which
does

   if (disk->rawio)
         qemuDomainObjTaint(driver, obj, VIR_DOMAIN_TAINT_HIGH_PRIVILEGES, logFD);
