Create new libvirt network with vlan based on openvswitched 2. Add multiple interfaces trunk untrunked to a few VMs 3. try to run a few VMs in a sequence. Sometime restart of libvirt helps Actual Results: Operation not permitted etc. Expected Results: VMs should start as it is on other distros tested on Fedora 20 which worked without issues -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
