QA:Testcase Virtualization Nic Bonding

Description

This test is intended to test nic bonding on virtual machine

How to test

1. determine the four nic models used in the test model1,model2,model3,model4

   qemu-kvm -net nic,model=model1,vlan=0 -net tap,vlan=0 -net nic,model=model2,vlan=1 -net tap,vlan=1 -net nic,model=model3,vlan=2 -net tap,vlan=2 -net nic,model=model4,vlan=3 -net tap,vlan=3 -m 1024 ......

2. configure the bonding interfaces configuration files:

   /etc/sysconfig/network-scripts/ifcfg-{ethnum}

   DEVICE={ethnum}

   USERCTL=no

   ONBOOT=yes

   MASTER=bond0

   SLAVE=yes

   BOOTPROTO=none

   /etc/sysconfig/network-scripts/ifcfg-bond0

   DEVICE=bond0

   BOOTPROTO=dhcp

   ONBOOT=yes

   USERCTL=no

3. modprobe the bonding module

   modprobe bonding

4. re-start the network interfaces

   service netowrk restart

5. use ifconfig to see if bond0 device have been setup and get the ip address ip_bond0

   ifconfig bond0

6. in the guest run the following scripts to down/up the interface eth0,eth1,eth2,eth3

   while true do;

   ifconfig eth0 down

   ifconfig eth0 up

   ifconfig eth1 down

   ifconfig eth1 up

   ifconfig eth2 down

   ifconfig eth2 up

   ifconfig eth3 down

   ifconfig eth3 up

   done

7. in the mean time ping the guest in host with the following command, the packet loss ratio should be zero

   ping _ip_bond0_ -c 1000

8. then flood ping the guest for two minutes

   ping -f _ip_bond0_ 

9. and then ping the guest, the packet loss ratio should be zero

   ping -c 100 _ip_bond0_

10. the packet loss should be zero.

Expected Results

1. test results should meet the requirements above
