host config: 
auto eth0
iface eth0 inet statis
	address 192.168.1.2
	netmask 255.255.255.0
	gateway 192.168.1.1

guest config:
iface eth0 inet statis
	address 192.168.1.3
	netmask 255.255.255.0
	gateway 192.168.1.1

Because requiring an additional bridge generates a lot of unresolved problems (migration?).
Isn't above setup simpler? - Normally, the user does not need to setup anything.

And AFAIK it works perfectly for hosters like hetzner/OVH which apply mac restrictions.
