As with other network services you need to bind the service on the host
to an IP not used by the guest. -i does that for portmap.
If you want to use portmap on the same IP on host and guest you are out
of luck.

The host sees all IPs of every guest.
If your services bind to portmap via the official IP it might even work,
no idea about the security stuff in that case.
Alternatively you can use a shared loopback interface, unlike the new
virtualized ones.
I'd consider 2 portmaps, 1 for teh host, 1 for the guest, 2 different
IPs and accept the fact that tehre are different IPs for idfferent
services.
