Description Stefan Berger 2010-05-07 18:25:25 UTC

Description of problem:

Support to setup of VEPA, i.e., the setup of the switch, needs a couple more patches that are currently being worked on and are expected to be posted by Monday (May 10, 2010).

Comment 2 RHEL Program Management 2010-05-07 20:04:57 UTC

This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux major release.  Product Management has requested further
review of this request by Red Hat Engineering, for potential inclusion in a Red
Hat Enterprise Linux Major release.  This request is not yet committed for
inclusion.

Comment 3 Daniel Veillard 2010-05-11 09:23:08 UTC

Okay, once the patches are finalized upstream and applied (hopefully quickly)
we should be able to add them, do we have all the required kernel support
already ?

Comment 6 Martin Jenner 2010-05-11 22:49:25 UTC

Red Hat QE does not have VEPA hardware to test this feature so cannot agree to
it's inclusion in RHEL 6.0 as we have no way to test it.

Comment 7 vivk 2010-05-12 00:29:52 UTC

The VEPA function requires the switch to do reflective relay. This can be simulated on a remote Linux host by setting the link in reflective relay mode. 

brctl addif <bridge> <interface>
echo 1 > /sys/class/net/<interface>/brport/hairpin_mode

The VEPA enabled system can then be tested against the Linux host configured as above. 

For the VDP protocol one would need hardware or a 'bridge' implementation to test.

Comment 9 Dave Allan 2010-05-26 14:47:53 UTC

libvirt-0.8.1-7.el6 has been built in RHEL-6-candidate with the fix.

Comment 11 Stefan Berger 2010-05-28 17:49:14 UTC

Where can this version be downloaded. It's not on DV's website.

Comment 12 Dave Allan 2010-05-28 19:22:48 UTC

DV is on vacation, so I did this build.  You can get src and x86_64 binary rpms at:

http://people.redhat.com/clalance/libvirt-el6/

Let me know if you need any others.

Comment 13 Chris Lalancette 2010-05-28 20:09:36 UTC

According to Stefan (the author of the VEPA patches), there are still missing patches to make VEPA work.  Flipping this back to ASSIGNED so we can pull those patches in.

Comment 18 Yan Tian 2010-08-25 02:40:45 UTC

Closed this bug based on reporter's comments.


Hi TianYan,

  Bug 590110 has been resolved a while ago from what I can tell. You or one of the owners of libvirt can close it. All 8021Qbg related outstanding bugs would be filed with a new bugreport.

  Bug 605187 had been resolved when the new version of libvirt was built. It can also be closed.

Regards,
   Stefan
