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.
