I think its reasonable to expect guest config changes on this new kind
of host. Would a link-down/link-up event work? I'm sure it will, there
is enough code floating around in the guests which handles cable unplug.

Do you mean netif_carrier_off() / netif_carrier_on()? They are already 
called in the code before this patch, but DHCP renew is not triggered by
them.
