[Users] ovirt 3.3 vnic profile with bonding & vlans problem

Thu Apr 3 13:50:29 EDT 2014

Hi Sven,

disclaimer, not familiar with this feature that much (although I should), looks like the problem is in libvirt (according to your story).
googling 'outbound libvirt not working' shows that you're not the only one :)
