Comment 16 for bug 1903267

I can not reproduce with 5.4.0-54.60 kernel, please let me know if my steps are wrong.

The attachment is the script I use to build VM guests on kunpeng920 machine
The net1.xml and net2.xml used in the scripts are

$ cat net1.xml
<hostdev mode='subsystem' type='pci' managed='yes'>
     <source>
             <address domain='0x0000' bus='0xbd' slot='0x01' function='0x0'/>
     </source>
</hostdev>

$ cat net2.xml
<hostdev mode='subsystem' type='pci' managed='yes'>
     <source>
             <address domain='0x0000' bus='0xbd' slot='0x01' function='0x1'/>
     </source>
</hostdev>

The netperf runs on TCP and UDP are passed.
