VM network needs connectivity to the internet

[achuzhoy]

The automated flow assumes there's internet connectivity for the default libvirt network.
Obviously the flow will fail if there's no connectivity, so we need to instruct he user to make sure there is one.

By default, the libvirt default network allows guests to create any outgoing network connection they like

I understand that this is related to installing IBI using disconnected environments, is that right @achuzhoy ?

So far, I think we should clarify in the README that for now there is no way for that, since we need connectivity/ISCP configuration for, at least:

• downloading RHCOS ISO (we would need to configure the host for that)
• pulling the seed image (arguably, since it can be pulled from an internal registry)
• precaching images (we would need to configure rhcos live system for that)

@javipolo it's just that we assume that there's connectivity.
I was working on a setup where the default network didn't have it.
