[Rdo-list] HA with network isolation on virt howto

Hi Marius,

the reason is that I would like for example to use internalapi network with
provisioning network in the same interface, and since provisioning doesn't
use bridge I wondered if this it's possible.

As I said, actually I was able to deploy overcloud with internalapi without
the bridge but I had to specify the physical interface "device: enps0f0" on
my heat template.

Thanks
Pedro Sousa
