ovirt is meant to manage your datacenter, so not the best match for
running with a wireless nic i guess.
vdsm may even be filtering it (danken?)
It is, because oVirt only supports bridge-based VM networks, and Linux
does not allow you to bridge a WiFi nic.
To work around this limitation, you could define a NAT-based network in
libvirt
http://libvirt.org/formatnetwork.html#examplesNAT and use it in
oVirt via vdsm-hook-extnet (a bit more about it in
http://developerblog.redhat.com/2014/02/25/extending-rhev-vdsm-hooks/ )
