Re: [libvirt] How to stop libvirt from deleting tap device after shutdown

Hi. I am currently setting up a new server machine which will host several kvm's managed largely by libvirt. The network setup though is done prior to libvirtd startup and shouldn't be touched by it. So currently everything works just fine with 0.6.0 except that libvirt deletes the tap device after I shut a kvm machine down which is something I naturally don't want. I looked through all the documentation I could find but I could not come up with a solution. Forgot to mention: all kvm machine are connected through a tap device with no bridge or whatsoever but 1:1 NAT. This done for performance reasons. As model I use "virtio".
