as usual, what tools, what host/guest distro?

should be sufficient with recent kernels to do an nfs mount
if the portmapper is reachable and working as expected

host but within the network context, which solves certain
issues you see, like requiring host and guest ip to be allowed

it fails, and check with rpcinfo and showmounts
