I need to configure Openstack on a Virtual Machine and for that I created an VLAN to support communication between controller and nodes. The problem is that I need internet access on this VLAN to download and install a few packages. My host computer is an Arch Linux distro and the guest (controller) is an Ubuntu Server Cloud.

I setted my VLAN this way:

$ ip link add link wlp2s0 name vlan.wifi type vlan id 100
$ ip addr add brd dev vlan.wifi   
$ ip link set dev vlan.wifi up

On my guest machine the IP is but I can't even ping my host!


The is "network" IP not the usable one.
