<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">I’m trying to find out if there is support in nova (in terms of metadata and cfgdrive) to configure vlan trunking in the guest. In the ‘CLI usage example’ provided in this wiki
<a href="https://wiki.openstack.org/wiki/Neutron/TrunkPort">https://wiki.openstack.org/wiki/Neutron/TrunkPort</a>, it indicates:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>

<span style="font-size:10.0pt;font-family:Monaco;color:#333333"># The typical cloud image will auto-configure the first NIC (eg. eth0) only and not the vlan interfaces (eg. eth0.VLAN-ID).<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-bottom:7.5pt;line-height:15.0pt;background:whitesmoke;word-break:break-all">
<span style="font-size:10.0pt;font-family:Monaco;color:#333333">ssh VM0-ADDRESS sudo ip link add link eth0 name eth0.101 type vlan id 101<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">I’d like to understand why the support of configuring vlan interfaces in the guest is not added. And should it be added?<o:p></o:p></span></p>
