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.

I do not know how to simulate a cable unplug. The point is that calling
/etc/init.d/network will fail, at least in SLES12.
Maybe some sort of "DHCP refresh required" event is required?
Maybe the DHCP clients need to renew on cable unplug?
No idea what the solution to the issue really is.

What's in the driver right now is definitely not it, and I want this
network restart code removed immediately.
