[pradeep <psuriset@linux.vnet.ibm.com>]

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

3. Netperf
--------------


RHEL 5.5: FAIL


RHEL6: FAIL

some tests fail with TCP_CRR, UDP_RR are failed. 
Looks like a bug..

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
