Network Patch set V4

Network Patch set V4

[pradeep]

Hi Lucas, i covered below  tests on RHEL 5.5 , RHEL 6 guests with vhost
enbled.  Please find the below errors and cause for errros.

I also attached few other test cases can be added to out TODO list of
network patchset. I am working on couple of these issues.

1. Nice_promisc:
-----------------
With RHEL 5.5: PASS

With RHEL 6: FAIL

its failing to login to the RHEL6 guest by serial. 


02:07:06 ERROR| Test failed: TestFail: Could not log into guest 'vm2'


2. nicdriver_unload 
--------------------------------

With RHEL 5.5: FAIL

With RHEL 6: FAIL

We may include below tests to for Network Patch set:
I am working on couple of issues among below mentioned. 

Ping6 testing

    * ping6 with various message sizes guest to/from local/remote host
      using link-local addresses 
      By default IPv6 seems to be disabled  on virbr0. Enable it by
      doing 

NIC bonding test :

https://fedoraproject.org/wiki/QA:Testcase_Virtualization_Nic_Bonding


NFS testing

    * create NFS server on guest, mount dir on host, copy and delete
      files, do reverse on host 

Setting and unsetting ethernet adapters.

       set_link name [up|down]

Multiple Nics Stress 
       Run parallel netperf sessions across multiple virtio-net NICs
       on  the guest

Thanks for your feedback, I will re-test them with rhel5/6 and reply the test result.

I have a draft patch for bonding testing, will improve and send it to mailist.

I only wrote a testcases, didn't automate it, could you help to review ?

Steps:
1. boot up a guest with virtio_nic
2. login guest through serial
3. transfer a big file from guest to host
guest) # scp a.out $host_ip:~
4. put down link by monitor
qemu) # set_link $nic_model.0 down
5. try to capture date by tcpdump
host)# tcpdump port $scp_port and src $guest_ip -i $tap
6. put up link by monitor
qemu) set_link $nic_model.0 down
7. try to capture date by tcpdump
host)# tcpdump port $scp_port and src $guest_ip -i $tap
8. transfer a big file from host to guest
host) # scp a.out $guest_ip:~
9. put down link by monitor
qemu) # set_link $nic_model.0 down
10. try to capture date by tcpdump
guest)# tcpdump port $scp_port and dest $guest_ip -i eth0
11. put up link by monitor
qemu) set_link $nic_model.0 down
12. try to capture date by tcpdump
host)# tcpdump port $scp_port and dest $guest_ip -i eth0

Expected Results:
4. it should not capture nothing
6. it should capture some packets
10. it should not capture nothing
12. it should capture some packets

I think we should use something simpler, like ping
guest-host and host-guest at the same time.

As Michel suggested, some thing simpler like Ping would be fine.
Apart from this every thing seems to be fine.

Hi Michael

could you share pointer to your tree which has rhel6 + vhost fixes.

Thanks
