There is no longer a need to modify the libvirt_vif_driver conf
setting, it should always be the default value of:
libvirt_vif_driver=nova.virt.libvirt.vif.LibvirtGenericVIFDriver
This patch removes any reference to deprecated options for the
libvirt_vif_driver parameter.
Closes-bug #1192833
As a side-effect, this patch removes a section that contains this note:
<note>
<para>When using libvirt < 0.9.11, one must also edit
<filename>/etc/libvirt/qemu.conf</filename>, uncomment the
entry for 'cgroup_device_acl', add the value '/dev/net/tun'
to the list of items for the configuration entry, and then
restart libvirtd.</para>
</note>
It's not clear to me whether this is required or not with the
generic VIF driver plugin.
