Hi Michal, Thanks for your answer. I don’t understand why an interface created without mtu gets only 1500 visible in the virtual machine but if I create an interface with mtu higher than 1500 e.g. 2000 the bridge will change too. Before the bridge was e.g. by 9000. I ask because you wrote if I don’t set an mtu of the interface I will get the mtu of the bridge. But it seems so. Can you clarify

Hi Alvin, Thanks for the help. :) This sounds good. My head also wrap about this problem. The question for me is why they use the smallest?

In general if no MTU is set on interface creation the default value is 1500. On OVS the bridge MTU is automatically set to the smallest port MTU. So you just have to set the MTU of each port of the bridge. Take a look at: https://bugzilla.redhat.com/show_bug.cgi?id=1160897 It is a bit of a pain to read but seems to confirm the statement about the OVS MTU value being set by the MTU of the

Hi, Is there an option to procure support for glusterfs deployment. ? As we moving into core production scenarios with glusterfs in mind, it would be slightly relieving to have this confirmation !!

Hi; I emailed monty@xiph.org about this before I noticed the mailing list existed; I suppose it can't ask to hurt here too. We're about to release a product which has support for multiple languages; as a result, the license text and documentation has been translated into each of these languages. As the product includes Ogg Vorbis playback using libvorbis, we've obviously got to

The error that you're showing doesn't appear to be related to permissions; the "ovs-vsctl del-port" command requires that you specify the port that you want to delete. --Justin On Mar 6, 2014, at 2:05 AM, Vasiliy Tolstov <v.tolstov@selfip.ru> wrote: > Hello!

Hi, my system got updated to libvirt 6.0.0 (from 5.6.0) this morning, and now I'm having problems starting VMs that make use of openvswitch portgroups.

Hi, I''m using XCP1.5beta, I´m trying to control the fake bridge created by "xe vlan-create" using NOX controller, is it possible? I tried ovs-vsctl set-controller <fake-bridge> but it claims the bridge is fake. I use NOX to control the parent bridge with set-fail-mode secure, so when I shoutdown the controller no more ping is possible,However it is possible to ping

Hell Friends,  came across a nice article and wanted to share. This one is for migrating OVS to a new OVM manager.  Doesnt come in the Oracle documentation so well, so here it is... http://sysengineers.wordpress.com/2010/07/21/migrating-a-running-ovs-to-a-new-ovm-howto/  Know this is Xen group, but Oracle VM is also xen based..  :-) Cheers...Deven.

Since UFO6 packets can now be identified by SKB_GSO_UDP6, add proper checks to handel UFO6 flows. Legacy applications may still have UFO6 packets identified by SKB_GSO_UDP, so we need to continue to handle them correclty.
