hi,all<br>      I am using <span>virDomainInterfaceStats to monitor the network flow of VM. But there is some strange things.<br>      the description of vnet in xml is:<br>      <br>      <interface type='bridge'><br>      <mac address='00:16:3e:5d:aa:a8'/><br>      <source bridge='br0'/><br>      <target dev='vnet0'/><br>      <model type='virtio'/><br>      <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/><br>      </interface><br><br>      but when I call virDomainInterfaceStats to get network flow from vnet0, I get some wrong data: <br><br>      rx: 139972719907412      tx:7311107385599290!
 735<br>      after 2 seconds, I call it again and I get:<br>      rx: 31                                tx:7311107385599290735<br>      another 2 seconds:  <br>      rx:155                               tx:7311107385599290735<br>      and...<br>      rx:110                               tx:7311107385599290735<br><br>      (rx:receive, tx:transmit)<br>!
      <br>     &nb!
 sp; what do these data mean? Why there is no difference in tx at all? And why the difference in rx is so weird?<br>       Many thanks!<br><br>regards<br>       zhangzhang<br>     <br><br>      <br><br></span>                                    </div></body>
