Commit Message

Ling, WeiX June 5, 2023, 6:34 a.m. UTC 
  As the DPDK commit a399d7b5(vfio: do not coalesce DMA mappings) changed,
We need to delete the `--no-huge -m 1024` parameter when start the
vhost-user as back-end side. So delete the `--no-huge -m 1024` parameter 
in testplan.

 3. On VM1, set virtio device IP and run arp protocal::
 
-    ethtool -L ens5 combined 8
-    ifconfig ens5 1.1.1.2
-    arp -s 1.1.1.8 52:54:00:00:00:02
+     ethtool -L ens5 combined 8
+     ifconfig ens5 1.1.1.2
+     arp -s 1.1.1.8 52:54:00:00:00:02
 
 4. On VM2, set virtio device IP and run arp protocal::
 
-    ethtool -L ens5 combined 8
-    ifconfig ens5 1.1.1.8
-    arp -s 1.1.1.2 52:54:00:00:00:01
+     ethtool -L ens5 combined 8
+     ifconfig ens5 1.1.1.8
+     arp -s 1.1.1.2 52:54:00:00:00:01
 
 5. Scp 1MB file form VM1 to VM2::
 
-    Under VM1, run: `scp [xxx] root@1.1.1.8:/` [xxx] is the file name
+     Under VM1, run: `scp [xxx] root@1.1.1.8:/` [xxx] is the file name
 
 6. Check the iperf performance between two VMs by below commands::
 
-    Under VM1, run: `iperf -s -i 1`
-    Under VM2, run: `iperf -c 1.1.1.2 -i 1 -t 60`
+     Under VM1, run: `iperf -s -i 1`
+     Under VM2, run: `iperf -c 1.1.1.2 -i 1 -t 60`
 
 7. Relaunch VM1, and rerun step 3.
