That is correct, setting the native vlan changes how an untagged packet is handled when it enters the port. The difference between the 'tagged' and 'untagged' modes is in how packets on the native vlan are processed before exiting the port. > And what happens when native_mode='yes' but there is no native_tag? In that case you configuration is invalid, and will get an error. > (that's what I was trying to describe with <tag id='123' > native='untagged'/>, but I don't even know if that makes sense, because > I don't know exactly what is the native vlan tag and what is done with > it :-) That arrangement would make sense, I chose the arrangement I did for two main reasons. There can only be one native vlan on a port, making it an attribute of the 'vlan' tag enforces this. Also, I wanted to keep the validation and processing separate rather than add 'if native' branches to the loops that operate on the vlan id list. I can see the advantage of having a single setting to configure the native vlan, rather than the two attributes I proposed. If the new suggestion is preferred I can rework my patch to use that format. > Also, is it valid to have a native_mode/native_tag if trunk='no'? (right > now trunk is automatically set to 'yes' if there is more than one vlan tag) It isn't valid to have trunk='no' and the native settings. Therefore "<vlan trunk='no' native_mode='tagged' native_tag='123'>" will get an error if you try to enter it. If no "trunk" attribute is set explicitly then it will be set to 'yes'. This means "<vlan native_mode='tagged' native_tag='123'>" is equivalent to "<vlan trunk='yes' native_mode='tagged' native_tag='123'>". > > > </network> > > diff --git a/tests/networkxml2xmlout/openvswitch-net.xml > > b/tests/networkxml2xmlout/openvswitch-net.xml > > index a3d82b1..ab3d797 100644 > > --- a/tests/networkxml2xmlout/openvswitch-net.xml > > +++ b/tests/networkxml2xmlout/openvswitch-net.xml > > @@ -21,4 +21,13 @@ > > <parameters profileid='alice-profile'/> > > </virtualport> > > </portgroup> > > + <portgroup name='tagged'> > > + <vlan trunk='yes' native_mode='tagged' native_tag='123'> > > + <tag id='555'/> > > + <tag id='444'/> > > + </vlan> > > + <virtualport> > > + <parameters profileid='tagged-profile'/> > > + </virtualport> > > + </portgroup> > > </network> > > > Protected by Websense Hosted Email Security -- www.websense.com

[libvirt] What about next release ?
by Daniel Veillard 23 Apr '13

23 Apr '13

We are getting quite close to the end of the month, if we want to stick to the 'end of month release' I guess we need to enter the freeze for 1.0.5 at the end of the week say Friday, and then push the release, assuming there is no big problem on Thursday next week (May 2, I could probably do it on May 1 but most civilized people will enjoy the May 1 day off so that should not change that much ;-) Daniel -- Daniel Veillard | Open Source and Standards, Red Hat veillard(a)redhat.com | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | virtualization library http://libvirt.org/
