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

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

RHEL 5.5: FAIL

RHEL6: FAIL

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

This is the reason for nic_promisc also.

file transfer pass from host to guest.
file transfer fail while transferring from guest to host

Need to debug further for this.

-----------------------------------------------------------------------------

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 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

8. transfer a big file from host to guest host) # scp a.out $guest_ip:~

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

Hi Michael

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

Thanks
Pradeep

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