Xen devel - Oct 2010 - [VLAN tagging on XenServer 5.6 with Dual Port 10GbE FCoE]

Hi,

we have a big problem, my hardware are two host XenServer 5.6 server IBM
x3850 with Dual Port 10GbE FCoE (qle8152) and switch Cisco nexus 5020

For the CNA driver I followed this instructions:
http://support.citrix.com/article/CTX126185/

After reboot, I have the new ethX (FCoE) and everything seems to work fine.

But we have a big problem only if we use the nic FCoE (10GbE) with the vlan
trunking.

(after configuring the switch and create the vlan on both XenServer)

- If I create 2 VMs on the same VLAN and on the same host, they can talk to
each other (ping and ssh and all protocols work correctly)

- If I create 2 VMs on the same VLAN on different hosts they cannot talk to
each other (ping are OK but ssh and all protocols TCP do not work properly)

We have tested on RedHat5.5 with xensource (on the same hardware) and the VM
(with vlan trunking) are ok.
But we want to use XenServer 5.6 and buy the license to use the support
because we have buy many hardware.

We opened a case to qlogic
http://solutions.qlogic.com/KanisaSupportSite/mysupport/viewsr.do?srNumber=70042682

Citrix has also opened a problem
http://solutions.qlogic.com/KanisaSupportSite/mysupport/viewsr.do?srNumber=70042926

Any idea ?

My first thought is that you have to disable TCP Checksum offloading.
There should be plenty of documentation on how to do this from a simple
Google search.

We are seeing the what appears to be the same problem on a HP BL465c using an
onboard Emulex 10GB card.  Traces show the same checksum errors reported
here.  

We removed the bond to get it out of the way.  But we''re still using
vlan
tagging.  we don''t have this issue if we move it to one of the
interfaces on
the 4 port Broadcom card.  Disabled checksum offloading in the WIN VM and in
XS on each of the PIFs and VIFs.

Emulex Firmware = 2.102.485.4
Emulex Driver = 2.102.313

For questions about XenServer, your best bet is to use the Citrix
forums.  You''ll get much better support there.  This is the place to
report errors relating to open-source Xen.
