Open Stack

Cynthia,

 Attaching a "regular KVM Virtual Machine" directly to the bridge, also did
not worked.

 I'll try to create this eth3.XXXX, a LinuxBridge "brqxxxxzzzz-yy" on top
of it and a new KVM VM, completely outside of OpenStack but, on top of this
very same server.

 Thanks again for the tip!
